The Medieval period is represented by several churchyard crosses. The defensive walls and part of Taunton Castle, which has Anglo-Saxon origins and was expanded during the Medieval and Tudor eras, is included. More recent sites include Poundisford Park, Buckland Priory, Bradford Bridge and a duck decoy from the 17th century. Some of the sites such as Balt Moor Wall are of uncertain date; however the most recent are air traffic control buildings, pillboxes and fighter pens from RAF Culmhead, situated at Churchstanton on the Blackdown Hills. The monuments are listed below using the titles given in the English Heritage data sheets.
