Pallas Castle is a tower house and National Monument located in County Galway, Ireland.

[6] In 1574 it was owned by Jonyck Fitzthomas Burke, but after the restoration it passed to the Nugent Earls of Westmeath.

The thick end wall contains a tier of mural chambers and a winding stair.

The fourth floor has attractive mullioned windows framed in arches.

The roof was still thatched in the early part of the 20th century, the bottom being covered with stone flags for protection.
