Description
Summary Description and Reason for Designation
The following provides a general description of the Scheduled Ancient Monument.
The monument comprises the remains of a motte dating to the medieval period (c. 1066 -1540 AD). A motte is a large conical or pyramidal mound of soil and/or stone, usually surrounded by either a wet or dry ditch, and surmounted by a tower constructed of timber or stone. Twyn Castell is a large steep-sided motte, with a flat top with a diameter measuring 15m.
The monument is of national importance for its potential to enhance our knowledge of medieval defensive practices. The monument is well-preserved and an important relic of the medieval landscape. It retains significant archaeological potential, with a strong probability of the presence of both structural evidence and intact associated deposits.
The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
