Carrigafoyle Castle is a formidable 15th-century tower house built between 1490 and 1500 by Conor Liath O'Connor on the Shannon Estuary near Ballylongford in County Kerry. Rising nearly 90 feet high with five storeys and a 104-step spiral staircase, this strategic fortress once commanded the shipping lanes supplying medieval Limerick. Its distinctive design includes a moat that would fill at high tide and a small dock for maritime access. The castle's dramatic history includes the famous 1580 siege during the Desmond Rebellion, and it remains one of Ireland's most impressive surviving tower houses.
