Gallarus Castle is a four-storey rectangular tower house built in the 15th century by the Knight of Kerry on the Dingle Peninsula in County Kerry. Located in the Gaeltacht village of Baile na nGall, this well-preserved fortified structure showcases typical late-medieval Irish architecture with split stone rubble construction and sandstone quoins. The tower retains its distinctive vaulted roof despite losing its original battlements, and sits just one kilometre from the ancient Gallarus Oratory, creating a significant historical pairing. Protected as a national monument, the castle offers insight into the Geraldine Dynasty's control of the region and has undergone careful restoration to preserve this important Irish heritage site.
