The Old Perth Courthouse is the city's oldest surviving building. It was built in 1836 to assert the supremacy of British law in the Swan River Colony and soon became integral to legal and civic life. It was designed in a classical 19th century Greek revival style and is one of two remaining examples of the work of Colonial Engineer Henry Revelly. It was also the scene of the infamous 1925 'Murder on the Dancefloor' trial of Audrey Jacob.
