Noted William Morrison designed this building in the late 1820s. It is one of Ireland’s finest examples of ancient Greek revivalist architecture. The Courthouse located on the site of a former quarry, has two large court rooms contained within the impressive granite decagonal shaped building. it is said to have cost £30,000 to construct. The Courthouse, based on the Temple of Llissus in Athens, gives the impression of a temple set on a high plinth, but this obscures the fact that the basement is a maze of cells and dungeons. A cannon from the Crimean Way stands on the steps. The Court House is operated under the Department of Justice.
