The courthouse, which was designed by Edward Parke and John Bowden in the neoclassical style and built in ashlar stone, was completed in 1819.

[1] The design involved a symmetrical main frontage facing Crowe Street; there was a short flight of steps leading up to a large hexastyle portico with fluted Doric order columns supporting a triglyphed entablature and a pediment.

[1] The design was modelled on the Temple of Hephaestus in Athens.

[2] The building was originally used as a facility for dispensing justice but, following the implementation of the Local Government (Ireland) Act 1898, which established county councils in every county, it also became the meeting place for Louth County Council.

[6] By then the courthouse had fallen into a state of disrepair and, after an extensive programme of refurbishment works, it was officially re-opened by Michael McDowell, the Minister for Justice, Equality and Reform, in March 2003.
