What to See in Mérida: Itinerary, Highlights & Tours
Mérida, the capital of Spain's Extremadura region, has the largest and best-preserved Roman ruins in the Iberian Peninsula. The city became a UNESCO World Heritage Site in 1993. Founded in 25 BC as Augusta Emerita by Emperor Augustus for retired soldiers, it later served as the capital of the Roman province of Lusitania. The Roman Theatre, built between 16 and 15 BC, seats 6,000 people and still hosts summer performances during the Classical Theatre Festival. Next to it, the Amphitheatre, built in 8 BC, once held 15,000 spectators for gladiator games. The Temple of Diana, with its 16 Corinthian columns from the 1st century AD, survived because it became the base for a Renaissance palace. The National Museum of Roman Art, designed by Rafael Moneo and opened in 1986, displays Roman mosaics, sculptures, and artifacts in a building inspired by Roman architecture. The Alcazaba fortress, built in 835 AD by emir Abd ar-Rahman II, is the oldest Islamic fortification in Spain and was constructed atop Roman ruins, using recycled materials. The Los Milagros Aqueduct, called the "Aqueduct of Miracles" for its 25-meter-high pillars, brought water from the Proserpina reservoir to the city. Other highlights include the 792-meter Roman Bridge over the Guadiana River, the Circus Maximus with seating for 30,000, and many excavated villas, baths, and monuments. Mérida, with about 60,000 residents, offers local Extremaduran food, a walkable historic centre, a mild climate, and a unique journey through Roman, Visigothic, and Islamic history.
The Roman Theatre (Teatro Romano), built between 16 and 15 BC under Emperor Augustus, is Mérida's most impressive monument and one of the best-preserved Roman theatres in the world. Its two-story stage backdrop is decorated with Corinthian columns, marble statues of emperors and gods, and detailed architectural features that create a dramatic setting for performances. The seating area, carved into San Albin hill, held 6,000 people, with senators in the front rows, middle classes in the middle, and slaves and women in the upper sections.
Remarkably, the theatre is still an active performance venue. The Mérida Classical Theatre Festival, held every July and August since 1933, presents Greek and Roman tragedies, Shakespeare adaptations, and other classical works in the same Roman setting where audiences sat 2,000 years ago. The mix of ancient architecture, summer nights, and live performances creates an unforgettable cultural experience.
The Roman Amphitheatre (Anfiteatro Romano), built in 8 BC next to the theatre, was the site of gladiator fights, animal hunts, and even mock naval battles when the arena was flooded. The oval-shaped building could seat about 15,000 people and had underground passages where gladiators and animals waited before entering the arena. Informational signs around the site explain the different types of gladiators, their training, and the rules of combat.
Both monuments are part of a single archaeological complex with joint admission, so visitors can appreciate the scale and sophistication of Roman entertainment.
Practical Info: Calle José Ramón Mélida; joint ticket €15 (includes Museum of Roman Art), theatre/amphitheatre only €12; open April-September 9am-9pm, October-March 9:30am-6:30pm; allow 1.5-2 hours; Classical Theatre Festival July-August (separate tickets required); accessible for reduced mobility; audio guides available; essential Mérida visit.
The National Museum of Roman Art (Museo Nacional de Arte Romano/MNAR), opened in 1986 and designed by renowned Spanish architect Rafael Moneo, displays an outstanding collection of Roman artifacts in a building that is just as impressive as the exhibits. Moneo used large red brick arches and high ceilings to echo the style of Roman architecture, so walking through the museum feels like stepping into a Roman basilica or bathhouse.
The museum displays a wide range of artifacts from Mérida's archaeological sites, spread across three well-organised floors. On the ground floor, you'll find large sculptures of emperors, gods, and mythological figures that once decorated public buildings and temples. The mosaic collection is among the best in Spain, featuring detailed floor mosaics from wealthy Roman homes depicting mythological stories, geometric designs, and scenes of daily life, all in excellent condition. Visiting the museum is a great complement to seeing the outdoor ruins, as the artifacts help you understand how Romans lived in Augusta Emerita, while the ruins show the city's urban planning and architecture.
Practical Info: Calle José Ramón Mélida 2 (adjacent to Roman Theatre); €6 entry, free Saturday afternoons and Sunday mornings; joint ticket with theatre/amphitheatre €15; open Tuesday-Saturday 9:30am-8pm, Sunday 10am-3pm, closed Monday; allow 1.5-2 hours; accessible; audio guides and bookshop available; air-conditioned respite from summer heat.
The Temple of Diana (Templo de Diana), despite its name, was actually dedicated to imperial cult worship, not the goddess Diana. This common mistake dates back to the Renaissance. Built in the 1st century AD as part of the municipal forum, the temple shows Roman provincial architecture with 16 fluted Corinthian columns still standing tall.
The temple is so well preserved because it was turned into a Renaissance palace in the 16th century for the Count of Los Corbos, who built the palace walls around the Roman columns. When parts of the palace were later removed, the original Roman structure was revealed and protected over the centuries. Today, the partially restored temple stands in the city centre, with a small museum inside that tells its story.
The Arch of Trajan (Arco de Trajano) is another misnamed monument, as it was built before Emperor Trajan and likely served as a grand entrance to the provincial forum rather than a triumphal arch. Standing 15 meters tall, this granite arch is one of the tallest Roman arches left in Spain and is a striking example of Roman engineering.
Both monuments appear on free walking tours explaining Mérida's Roman urban planning and imperial propaganda through monumental architecture.
Practical Info: Temple of Diana on Calle Sagasta; free exterior viewing anytime, small museum inside; Arch of Trajan on Calle Trajano; both centrally located and easily walked between; allow 30-45 minutes combined; excellent photo opportunities; integrate into walking tour of Roman centre.
The Alcazaba de Mérida, constructed in 835 AD by Umayyad emir Abd ar-Rahman II, represents the oldest Islamic fortification preserved in the Iberian Peninsula. The fortress was built to control Mérida, which had rebelled against Cordoban emirate authority since 805, demonstrating the city's continued strategic importance centuries after the Roman era.
The square fortress is 130 meters on a side and has 10-meter-high walls made from recycled Roman materials, including granite blocks, columns, inscriptions, and fragments from old Roman buildings. Twenty-five square towers strengthen the walls and provide defensive positions. This use of older materials, known as spolia, shows a practical medieval approach and creates an interesting mix of different civilisations.
Inside the walls, excavated Roman ruins include portions of earlier structures on which Muslims built, while a sophisticated aljibe (cistern) collected and filtered water from the Guadiana River for the fortress garrison. Access from the adjacent Roman Bridge passes through a small enclosure (Alcarazejo) that controlled pedestrian and goods traffic.
From the fortress walls, you can see the Guadiana River, the Roman Bridge, and the modern city. It's a great spot to get a sense of Mérida's defensive layout and how the city has changed over time.
Practical Info: Calle Graciano; €5 entry; open April-September 9am-3pm & 5pm-9pm, October-March 9:30am-1:45pm & 4pm-6:15pm; allow 1 hour; combine with Roman Bridge walk; accessible for reduced mobility with some limitations; interesting contrast to Roman sites.
The Acueducto de los Milagros (Aqueduct of Miracles), built in the 1st century AD, got its name from locals who were amazed by its survival and impressive engineering. The aqueduct carried water 12 kilometres from the Proserpina reservoir to Augusta Emerita, using a carefully designed gravity-fed system.
The remaining part of the aqueduct crosses the Albarregas River valley and has 38 arched pillars that reach up to 25 meters high. The double rows of granite pillars and brick arches create a striking red-and-gray striped look. As the valley gets deeper, the pillars and arches get taller to keep the water flowing at the right level. At the northern end, you can see the remains of a settling pool that cleaned the water before it entered the city.
The aqueduct, which is part of the UNESCO World Heritage site, stands in a quiet park where locals like to take evening walks. The pillars reflect in the pools, creating a romantic scene, especially at sunset.
The Puente Romano (Roman Bridge) stretches 792 meters across the Guadiana River and is one of the longest surviving Roman bridges in the world. Built in the 1st century BC during Augustus's reign and modified over the centuries, the bridge was part of the Via de la Plata (Silver Route) connecting Mérida to Astorga in northern Spain. Now fully pedestrian, the bridge offers great views of the Alcazaba walls, the river, and the city skyline. It's perfect for a leisurely walk while imagining the Roman legions, merchants, and pilgrims who once crossed here.
Practical Info: Los Milagros Aqueduct on Avenida Vía de la Plata (northern outskirts); free access anytime; 20-minute walk from centre or short bus ride; allow 30-45 minutes. Roman Bridge connecting Alcazaba to the opposite riverbank; free pedestrian access anytime; allow 20-30 minutes crossing; combine visits for comprehensive Roman infrastructure appreciation.
Plaza de España is the social heart of Mérida. This spacious 19th-century square is surrounded by elegant buildings, cafés, restaurants, and shops, creating a lively atmosphere. The plaza is home to the Concatedral de Santa María (Co-Cathedral), which was built on top of Roman and Visigothic remains. Weekly markets and cultural events bring the area to life. It's the perfect spot for refreshments, people-watching, and experiencing local life after visiting the city's monuments.
The Basilica of Santa Eulalia honours Mérida's patron saint, who was martyred during Roman persecution around 304 AD. A visit includes three main parts: the impressive Visigothic basilica, rebuilt in the 13th century on earlier foundations; the 1612 martyrdom shrine, which stands on the street; and the remarkable archaeological crypt below.
The underground crypt shows the remains of a Roman house, an early Christian cemetery, and the foundations of a Visigothic church, all layered on top of each other. Walking through these underground passages, you can see how Christian sites were built directly over Roman structures, indicating continuous use of the area from Roman times through the Visigothic period and beyond.
Practical Info: Plaza de España in the city centre; free access anytime; numerous cafés: €2-4 for coffee, €8-15 for meals. Santa Eulalia Basilica on Avenida de Extremadura; €4 entry includes crypt and archaeological area; open Tuesday-Saturday 9:30am-1:45pm & 5pm-7:15pm, Sunday 9:30am-1:45pm; allow 45-60 minutes; fascinating religious archaeology.

Augusta Emerita, Mérida's Roman name meaning "Augustan City of the Veterans," was founded in 25 BC by Emperor Augustus as a retirement colony for soldiers from legions V Alaudae and X Gemina who had completed service in the Cantabrian Wars. The city's strategic position at the Guadiana River crossing on the Via de la Plata connecting southern and northern Hispania ensured rapid growth.
As the capital of Lusitania province encompassing modern Portugal and western Spain, Augusta Emerita became one of the empire's most important cities. The 1st centuries BC-AD witnessed the construction of monumental architecture—the theatre, amphitheatre, circus, aqueducts, temples, baths, and bridges—transforming the colony into a showcase of Roman urban planning and engineering. The city's prosperity derived from administration, agriculture, mining, and its position controlling major trade routes.
After the fall of the Western Roman Empire (5th century), the Visigothic Kingdom established Mérida as an important episcopal centre. The 6th-century bishops wielded considerable power, and the city briefly served as the capital of Hispania. Visigothic architecture, including the foundations of Santa Eulalia Basilica and numerous churches, was layered atop Roman structures.
The Muslim conquest in 713 AD under Musa ibn Nusayr incorporated Mérida into Al-Andalus, making it the capital of the cora (administrative district) of Mérida. The Arabs reused Roman buildings and expanded infrastructure, most notably constructing the Alcazaba fortress in 835 using Roman spolia. The Islamic period brought architectural fusion and continued urban importance.
Christian reconquest in 1230 by Alfonso IX of León reintegrated Mérida into the Christian kingdoms. The medieval and Renaissance periods saw population decline and abandonment of many Roman structures, ironically aiding preservation by limiting destructive reuse. The 18th-19th centuries brought renewed interest in Roman remains as archaeological sites rather than quarries.
Modern archaeological excavation, beginning in the early 20th century, revealed extraordinary preservation. The 1933 inauguration of the Classical Theatre Festival revitalised the Roman Theatre, while systematic excavations uncovered more monuments. UNESCO World Heritage designation in 1993 recognised the site's universal value. The 1986 opening of Rafael Moneo's National Museum of Roman Art established a world-class facility for artifacts. Today Mérida balances modern regional capital functions with archaeological tourism, preserving 2,000 years of layered civilisations.

Roman Theatre & Amphitheatre
The Roman Theatre (Teatro Romano), built between 16 and 15 BC under Emperor Augustus, is Mérida's most impressive monument and one of the best-preserved Roman theatres in the world. Its two-story stage backdrop is decorated with Corinthian columns, marble statues of emperors and gods, and detailed architectural features that create a dramatic setting for performances. The seating area, carved into San Albin hill, held 6,000 people, with senators in the front rows, middle classes in the middle, and slaves and women in the upper sections.
Remarkably, the theatre is still an active performance venue. The Mérida Classical Theatre Festival, held every July and August since 1933, presents Greek and Roman tragedies, Shakespeare adaptations, and other classical works in the same Roman setting where audiences sat 2,000 years ago. The mix of ancient architecture, summer nights, and live performances creates an unforgettable cultural experience.
The Roman Amphitheatre (Anfiteatro Romano), built in 8 BC next to the theatre, was the site of gladiator fights, animal hunts, and even mock naval battles when the arena was flooded. The oval-shaped building could seat about 15,000 people and had underground passages where gladiators and animals waited before entering the arena. Informational signs around the site explain the different types of gladiators, their training, and the rules of combat.
Both monuments are part of a single archaeological complex with joint admission, so visitors can appreciate the scale and sophistication of Roman entertainment.

National Museum of Roman Art
The National Museum of Roman Art (Museo Nacional de Arte Romano/MNAR), opened in 1986 and designed by renowned Spanish architect Rafael Moneo, displays an outstanding collection of Roman artifacts in a building that is just as impressive as the exhibits. Moneo used large red brick arches and high ceilings to echo the style of Roman architecture, so walking through the museum feels like stepping into a Roman basilica or bathhouse.
The museum displays a wide range of artifacts from Mérida's archaeological sites, spread across three well-organised floors. On the ground floor, you'll find large sculptures of emperors, gods, and mythological figures that once decorated public buildings and temples. The mosaic collection is among the best in Spain, featuring detailed floor mosaics from wealthy Roman homes depicting mythological stories, geometric designs, and scenes of daily life, all in excellent condition.

Temple of Diana & Arch of Trajan
The Temple of Diana (Templo de Diana), despite its name, was actually dedicated to imperial cult worship, not the goddess Diana. This common mistake dates back to the Renaissance. Built in the 1st century AD as part of the municipal forum, the temple shows Roman provincial architecture with 16 fluted Corinthian columns still standing tall.
The temple is so well preserved because it was turned into a Renaissance palace in the 16th century for the Count of Los Corbos, who built the palace walls around the Roman columns. When parts of the palace were later removed, the original Roman structure was revealed and protected over the centuries. Today, the partially restored temple stands in the city centre, with a small museum inside that tells its story.
The Arch of Trajan (Arco de Trajano) is another misnamed monument, as it was built before Emperor Trajan and likely served as a grand entrance to the provincial forum rather than a triumphal arch. Standing 15 meters tall, this granite arch is one of the tallest Roman arches left in Spain and is a striking example of Roman engineering.
Both monuments appear on free walking tours explaining Mérida's Roman urban planning and imperial propaganda through monumental architecture.
Practical Info: Temple of Diana on Calle Sagasta; free exterior viewing anytime, small museum inside; Arch of Trajan on Calle Trajano; both centrally located and easily walked between; allow 30-45 minutes combined; excellent photo opportunities; integrate into walking tour of Roman centre.
Alcazaba Fortress
The Alcazaba de Mérida, constructed in 835 AD by Umayyad emir Abd ar-Rahman II, represents the oldest Islamic fortification preserved in the Iberian Peninsula. The fortress was built to control Mérida, which had rebelled against Cordoban emirate authority since 805, demonstrating the city's continued strategic importance centuries after the Roman era.
The square fortress is 130 meters on a side and has 10-meter-high walls made from recycled Roman materials, including granite blocks, columns, inscriptions, and fragments from old Roman buildings. Twenty-five square towers strengthen the walls and provide defensive positions. This use of older materials, known as spolia, shows a practical medieval approach and creates an interesting mix of different civilisations.

Short History
Augusta Emerita, Mérida's Roman name meaning "Augustan City of the Veterans," was founded in 25 BC by Emperor Augustus as a retirement colony for soldiers from legions V Alaudae and X Gemina who had completed service in the Cantabrian Wars. The city's strategic position at the Guadiana River crossing on the Via de la Plata connecting southern and northern Hispania ensured rapid growth.
As the capital of Lusitania province encompassing modern Portugal and western Spain, Augusta Emerita became one of the empire's most important cities. The 1st centuries BC-AD witnessed the construction of monumental architecture—the theatre, amphitheatre, circus, aqueducts, temples, baths, and bridges—transforming the colony into a showcase of Roman urban planning and engineering. The city's prosperity derived from administration, agriculture, mining, and its position controlling major trade routes.
After the fall of the Western Roman Empire (5th century), the Visigothic Kingdom established Mérida as an important episcopal centre. The 6th-century bishops wielded considerable power, and the city briefly served as the capital of Hispania. Visigothic architecture, including the foundations of Santa Eulalia Basilica and numerous churches, was layered atop Roman structures.
The Muslim conquest in 713 AD under Musa ibn Nusayr incorporated Mérida into Al-Andalus, making it the capital of the cora (administrative district) of Mérida. The Arabs reused Roman buildings and expanded infrastructure, most notably constructing the Alcazaba fortress in 835 using Roman spolia. The Islamic period brought architectural fusion and continued urban importance.
Christian reconquest in 1230 by Alfonso IX of León reintegrated Mérida into the Christian kingdoms. The medieval and Renaissance periods saw population decline and abandonment of many Roman structures, ironically aiding preservation by limiting destructive reuse. The 18th-19th centuries brought renewed interest in Roman remains as archaeological sites rather than quarries.
Modern archaeological excavation, beginning in the early 20th century, revealed extraordinary preservation. The 1933 inauguration of the Classical Theatre Festival revitalised the Roman Theatre, while systematic excavations uncovered more monuments. UNESCO World Heritage designation in 1993 recognised the site's universal value. The 1986 opening of Rafael Moneo's National Museum of Roman Art established a world-class facility for artifacts. Today Mérida balances modern regional capital functions with archaeological tourism, preserving 2,000 years of layered civilisations.
