Arkin's Castle

Arkin's Asstle (Caisleán Aircín) is a 13th-century ruined castle on the island of Inishmore, County Galway, Ireland. It is owned by the Department of the Environment, Climate and Communications of Ireland.

History
Likely built by the O'Brien family in the 1200s, it passed through various owners in the 16th and 17th centuries, including Teige Ó Flaithbheartaigh in 1607. By the 1650s, the original structure had been demolished and a new, enlarged fort was built for Oliver Cromwell, where he stationed soldiers throughout the 1660s. Since the 1700s, it has been uninhabited. Today the ruins include part of a wall and water-gate to the north, a tower at the south-east corner, and a bartizan.

The castle is listed on the Record of Monuments and Places as GA119-005 and National Monument number 43.01.
