Potsdam, the capital of Brandenburg, sits 30km southwest of Berlin along the Havel River and is often called Prussia's crown jewel. This UNESCO World Heritage site features 17 palaces built over three centuries, showcasing Enlightenment ideals through terraced vineyards, Rococo palaces, and Baroque architecture. Starting in 1685, the Hohenzollern rulers transformed Potsdam from a small garrison town into Prussia's summer capital. Frederick the Great's reign (1740–1786) is reflected in the intimate Sanssouci Palace, his 'sans souci' or 'without worries' Rococo retreat, and the grand New Palace, built after the Seven Years' War with 200 rooms and 428 statues. The Dutch Quarter, with 134 red-brick houses, is the largest Dutch enclave outside the Netherlands and is now home to artisan workshops. English-style gardens, lakes, and forests create a park-like setting. Cecilienhof Palace is where Churchill, Truman, and Stalin met in 1945 for the Potsdam Conference, which shaped postwar Europe. Free walking tours from Old Market Square or Museum Barberini help visitors explore over 280 years of Prussian history, stunning architecture, and Cold War sites, including royal terraces, the Dutch Quarter, Brandenburg Gate, Babelsberg film studios, and lakeside promenades.

Cologne is the largest city in western Germany and sits on the Rhine River, blending 2,000 years of history. Once the Roman provincial capital called Colonia Claudia Ara Agrippinensium, it later became a major medieval trade center. The city’s most famous landmark is the Cologne Cathedral (Kölner Dom), a UNESCO World Heritage site with twin spires reaching 157 meters. The cathedral survived 262 bombing raids during World War II and became a symbol of resilience for both Allied pilots and those who rebuilt the city. Today, about 1.08 million people live in Cologne, which is known for its special "Kölsche Jeföhl"—a relaxed, humorous, and welcoming spirit that’s different from the usual Prussian image. Cologne is the cultural heart of North Rhine-Westphalia, famous for its lively Carnival (especially the Rosenmontag parade in February, which draws 1.5 million people), its protected Kölsch beer (served in small glasses by blue-aproned Köbes waiters), and its Old Town, where pastel-colored buildings hide Roman ruins and medieval squares. Free walking tours from Freetour.com, starting at the Eigelstein-Torburg gate or Heumarkt’s riverside breweries, help visitors explore the city’s many layers, from Romanesque churches and Hanseatic League history to the destruction of WWII and the city’s modern revival. Today, you can visit the Lindt Chocolate Museum, walk along the Rhine promenade, see the love-locks on the Hohenzollern Bridge, and stop by more than 300 Brauhäuser that keep Cologne’s brewing traditions alive.

Munich, the capital of Bavaria, sits between the Isar River and the northern foothills of the Alps. The city has a rich history, from its beginnings as a salt-trade toll station in 1158 to the grand Residenz palace built by the Wittelsbach dynasty. Munich also witnessed some of the darkest moments of the 20th century, as the Nazi Party rose to power here. Today, the city blends its engineering achievements (like BMW Welt and the Deutsches Museum), beautiful Baroque churches, and a lively beer culture that hosts the world’s largest folk festival. With 1.56 million residents, Munich feels both vibrant and welcoming, with tree-lined streets, the famous Hofbräuhaus filled with music, and Viktualienmarkt food stalls serving Weisswurst breakfasts with pretzels and beer. The city is a major economic center in southern Germany, but it also preserves its history, from the Frauenkirche’s twin domes to Marienplatz’s Glockenspiel and the Feldherrnhalle at Odeonsplatz, which marks the site of the 1923 Beer Hall Putsch. Free walking tours from Freetour.com, starting at the Altes Rathaus’s Juliet Capulet statue, guide visitors through Munich’s layered story—from Roman times and the Wittelsbachs, through Bismarck’s unification, the Nazi era, and the bravery of the Weiße Rose student resistance. All of this is set against the backdrop of the 1516 Reinheitsgebot beer purity law, which led to the city’s 600-plus breweries.

Albarracín sits on a bend of the Guadalaviar River in Aragon's Sierra de Albarracín. It's one of Spain's prettiest villages, with rose-colored stone houses that seem to tumble down cliffs surrounded by pine forests and ancient rock art. With only about 1,000 residents, this well-preserved medieval town was named a Historic-Artistic Monument in 1961. Its narrow cobbled streets wind past wooden balconies that jut out over the lanes, ochre walls that glow at sunset, and Mudéjar plasterwork that mixes Islamic and Gothic styles. Albarracín began as a Moorish taifa kingdom in the 10th century under the Berber Banu Razín dynasty. It remained semi-independent through the Reconquista, with its pink cliffs helping to defend against sieges until Pedro III took control in 1284. Today, visitors can explore unique houses like Casa de Julianeta, see lizard carvings on doorways, visit the Torre del Andador, and spot noble coats of arms at Monterde-Antillón. Free walking tours from Plaza Mayor reveal everything from Islamic ceramics to medieval law codes in the Museo de Albarracín.

Huelva is a port city in southwestern Andalusia, Spain, where the Tinto and Odiel rivers meet the Atlantic. With about 145,000 residents, it is the capital of Huelva province and a starting point for the Costa de la Luz and Doñana National Park. The city’s history goes back to the Phoenicians in the 9th century BC, followed by Romans and Moors, who helped it grow through fishing, mining, and trade. Huelva is best known for its link to Columbus: he prepared for his 1492 voyage at the nearby La Rábida monastery in Palos de la Frontera, where his three ships set sail for the Americas. Today, visitors can see Casa Colón, wander the historic centre around Plaza de las Monjas, walk along the Muelle del Tinto pier, and enjoy the beaches and the UNESCO-listed Marismas del Odiel wetlands. Free walking tours are a great way to discover Huelva’s history, architecture, and maritime traditions, making them perfect for first-time visitors.

Soria is in north-central Castile and León, set along the Douro River. The city blends ancient Celtiberian history, a strong literary tradition, and beautiful natural surroundings. Just 7 km north, the Numancia Archaeological Site preserves the Celtiberian city that famously resisted a Roman siege for 13 months (134-133 BC) before its people chose death over surrender. The Church of Santo Domingo, built in the 12th century, has one of Spain's finest Romanesque facades, with detailed sculptures and a striking rose window. Soria is called the "City of Poets" because writers like Gustavo Adolfo Bécquer, Antonio Machado, and Gerardo Diego found inspiration here. The Ermita de San Saturio, an 18th-century baroque hermitage on a rocky outcrop above the river, contains frescoes and marks the place where the city's patron saint lived. Outside Soria, you can visit Laguna Negra de Urbión, a glacial lake surrounded by pine forests and cliffs, and the Cañón del Río Lobos, a 25-km limestone gorge with the 12th-century Ermita de San Bartolomé. Soria's signature dish is torreznos de Soria: crispy fried strips of cured pork belly with a Quality Guarantee certification.

Vitoria-Gasteiz, the capital of Álava and the Basque Country, combines its medieval roots with a strong focus on sustainability. The old town still has its original almond-shaped layout, created when King Sancho VI "The Wise" founded the city more than 800 years ago. The Gothic Cathedral of Santa María, currently being restored through the "Open for Works" program that won the Europa Nostra 2000 award and inspired Ken Follett's novels, stands at the top of the old quarter. The cobbled streets are named after medieval trades like Herrería (ironworkers), Zapatería (shoemakers), and Cuchillería (knifemakers). Plaza de la Virgen Blanca is the heart of the city, featuring the Battle of Vitoria monument and San Miguel Church, which holds the shrine of the city's patron Virgin. Vitoria-Gasteiz was named European Green Capital in 2012 and Global Green City in 2019, and offers 46 square meters of green space per person, including a 30 km Green Ring of parks. The city’s pintxos bars are famous, with places like El Toloño serving the best Gilda and Sagartoki winning Best Pintxos Bar of Spain twice.

The well-known As Burgas springs reach over 60°C as they come out of granite rock, giving you a special thermal experience in Spain. In addition to the hot springs, Ourense Cathedral features the impressive Pórtico del Paraíso, a 13th-century masterpiece that stands alongside Santiago de Compostela’s famous portico.
