Dublin Castle

Frommer's Review

This 13th-century structure was the center of British power in Ireland for more than 7 centuries, until the new Irish government took it over in 1922. You can walk the grounds for free, although this is largely municipal office space now and is disappointingly dominated by parking lots. Still, it's worth a wander; highlights include the 13th-century Record Tower; the State Apartments, once the residence of English viceroys; and the Chapel Royal, a 19th-century Gothic building with particularly fine plaster decoration and carved-oak gallery fronts and fittings. If they're open, check out the Undercroft, an excavated site on the grounds where an early Viking fortress stood, and the Treasury, built in the early 18th century. There are also a vaguely interesting on-site craft shop, heritage center, and restaurant.
