Ludlow Castle is an extensive stone keep and bailey fortress, the entire castle surviving intact, founded by the de Lacy family. The outer bailey curtain wall is well preserved and retains its battlements, an altered gatehouse, a square Norman flanking tower and the U-shaped Mortimer's Tower. In the large outer bailey are lodgings, a prison, stables and the Chapel of St Peter all backing onto the curtain wall. In the north-west corner is the inner bailey, with its steep rock-cut ditch and surrounding curtain wall flanked by four open backed square towers. The original Norman gatehouse has been blocked and raised to become a keep, flanking a plain arched gateway, which leads to a classic range of buildings and an unusual circular Norman chapel. 4 miles south-west is Aston Tump and 7 miles south is Ashton Castle.
