Located along the river Liffey in one of the oldest parts of Dublin is the country's most visited attraction and home of the nation's most iconic and famous brand export, the Guinness Storehouse.
The storehouse is a 'pint-shaped' wonderland in St. Jame's brewery charting the story & cultural legacy of Guinness throughout seven floors, on top of which sits the Graity bar offering delicious pints of the black stuff complimented by fascinating 360 degree panaromic views of Dublin's cityscape.
Open daily from 9:30am with last admission at 5pm (6pm in Summer season), the experience is self-guided and at €20 for an adult ticket (10% discount when booked online) & €16 for students it's not exactly cheap but seeing & learning the heritage and history of Guinness and it's very important role in national history and culture before enjoying a pint from source is really a great, worthwhile experience.
