At the junction of Shop Street and Upper Abbeygate Street is Lynch's Castle, a 16th century castle which was heavily altered in 1966 when it was converted into a bank. The exterior preserves some of the few remaining Irish gargoyles as well as the arms of Henry VII, the Lynch family and the Fitzgeralds of Kildare. The stonework of the windows is of good quality. On the ground floor, historical material dealing with the castle is displayed.
A doorway and first-floor window of one of the many fine 16th and 17th century houses which adorned the city has been re-erected in isolation on the north side of Eyre Square. It belonged to a house of the Browne family which formerly stood on Lower Abbeygate Street.
