Considered the finest town castle in Ireland, this old stone town house – now part of AIB Bank – was built in the 14th century, though much of what you see today dates from around 1600. Stonework on the facade includes ghoulish gargoyles and the coats of arms of Henry VII, the Lynches (the most powerful of the 14 ruling Galway 'tribes') and the Fitzgeralds of Kildare. On the inside, it's worth a gander at the hefty and magnificent fireplace.
