 The old keep was of three storeys and a garret, above a corbelled-out parapet with machicolations and water spouts.An old ceiling was removed in 1917 to reveal an ancient wooden ceiling, which carried writing alluding to the Stewarts, and the date was 1325; in the 2010s, part of the text was reproduced on stone as a public art installation at Cuningar Loop, a recently-opened public park a short distance to the north of the site of the castle.The castle was a simple keep of the 15th century, possibly built on an older core.
