The complex is entered from Grosvenor Road through the Propylaeum, a Grade I listed building. This consists of a massive entablature supported on widely spaced ("areostyle") Doric columns, flanked by temple-like lodges. Directly ahead is the former Shire Hall (also listed Grade I) which now houses the Crown Courts. Its façade has 19 bays, the central seven bays of which project forward and constitute a Doric portico. To the left is the former barracks block which is now the home of the Cheshire Military Museum. To the right is the block which was originally an armoury and later an officers' mess. Both blocks are in neoclassical style and are listed Grade I.
