Three large walls still remain of the castle, which was turned into a hunting lodge by Henry III but fell into disuse by the 15th century.

The southern enclosure, which lies within them and at the opposite end of the site from the standing walls, is thought to have been an Iron Age stronghold.

[1] A medieval castle was probably first built in the late 11th century by Edward of Salisbury, Sheriff of Wiltshire.

He strengthened it and may have added the northern enclosure, which contained the important buildings, largely in stone, including a great hall and a tower with royal living quarters.

[2] Ludgershall was a more important place in medieval England than it is now, and was able to send two members to Parliament, a privilege it kept until the Reform Act 1832.
