Carlow Courthouse, Neoclassical courthouse in Carlow, Ireland

Carlow Courthouse is a neoclassical judicial building in Carlow, Ireland, rising on an elevated site above Dublin Road. It features a prominent front portico with eight Ionic columns set on a raised platform.

Carlow Courthouse was designed by William Vitruvius Morrison in the neoclassical style and completed in 1834, built in ashlar stone. Its symmetrical front faces the corner of Athy Road and Old Dublin Road, with an octastyle Ionic portico modelled on the Temple on the Ilissus in Athens. After the Local Government (Ireland) Act 1898 it also housed meetings of Carlow County Council, and it was refurbished in 2002.

The building still serves as a working courthouse where legal proceedings take place, embodying how Ireland represented its public institutions in the 1800s. The neoclassical design reflects the values of order and authority that shaped the nation's official architecture.

The courthouse stands at the corner of Athy Road and Old Dublin Road, with its main frontage facing that junction. A flight of steps climbs to the octastyle portico, so the entrance is approached from above street level. It remains a working judicial facility, refurbished in 2002, so interior areas are not open to casual visitors.

A Russian artillery piece used in the Crimean War was brought back to Ireland and placed on the courthouse steps in 1858. It remains there today, a military object set against Morrison's Ionic portico.
