Glenquin Castle, County Limerick
Ireland abounds with fortified tower houses, and Glenquin Castle is one of the best. Rising 70ft and seven storeys high, it is a remarkable mid-15th-century structure, with a spiral staircase linking three high-vaulted rooms, one above the other. Traces of wicker shuttering can be seen on the ceilings of two private chambers.
Glenquin Castle is a real hidden gem that is worth a visit on your Ireland tours.
