Temple Bar

Dublin's cobbled cultural quarter, best known for its red-fronted pub of the same name — genuinely touristy but still worth a pint, ideally at a quieter neighbouring pub instead.

Ireland's largest cathedral, founded in 1191, with ties to Jonathan Swift (author of Gulliver's Travels), who served as dean here and is buried inside.

5

Grafton Street

Dublin's premier pedestrian shopping street, usually filled with buskers — often the first stop for visitors staying near St Stephen's Green.

6
