St. James' Gate, Ushers, Dublin 8, Ireland Guinness Factory Tour
It’s number one for a reason. This one’s essential to tick off any stag do in the Irish city. The birthplace of the country’s best expat (other than Robbie Keane) is the city’s most popular attraction, with seven floors of Guinness history to explore. The giant pint glass of a building (which can hold 14.3 million pints of the good stuff, FYI), has seen the likes of Taylor Swift, Barack Obama, Tom Cruise, the entire Lord of the Rings cast and even The Queen pass through its gates – and if it’s good enough for them, it’s good enough for your stag do. A trip to the Guinness Storehouse is educational, cultural and you can sink a few pints in the Gravity Bar at the top, too. Everyone’s a winner.
