The castle comprises three circular towers—the Keep, the Kitchen Tower and the Well Tower—along with the Hall Block, the Gatehouse and a shell wall; the buildings almost entirely encase the original motte in stone. The older parts of the castle are constructed from crudely laid red sandstone rubble and grey limestone, the 19th-century additions in more precisely cut red Pennant sandstone. A ditch is cut out of the rock in front of the Gatehouse and leads to an eastern approach road. The castle is surrounded by woodland and the 19th-century vineyards below it have been converted into a golf course. In 1850, George Clark recorded an "outer court" of which nothing remains; this may, in fact, have been the traces of the earlier lime kiln operations around the site.
