[1] Motte-and-bailey castles date back to the medieval period, from 1066 to 1540 AD.

[1] Recently a broken piece of French polychrome pottery ware was found on the site.

There is no record of the motte as to its exact age, although as with other mottes in the north of Cardiff, such as Treoda Castle Mound and Twmpath Castle, it is believed that it was established between the late 11th century and early 12th century.

It retains significant archaeological potential, with a strong probability of the presence of both structural evidence and intact associated deposits.
