In 1194, the castle was recaptured by the English with the purpose of reopening the mines on Llanymynech Hill and extracting silver. Richard I had been captured and held for a ransom of £100,000, and the Bishop of Salisbury, Hubert Walter, heard of the discovery of silver at the Carreghofa Mine on Llanymynech Hill; he decided to develop the mine and reopen the mint at Shrewsbury to refine the silver and make it into coins. Unfortunately, the total amount of silver produced only came to the value of £20, 11 shillings and 11 pence. This mine was located north of the present quarry, and just south of the present golf course clubhouse. In the 1230s, the castle was destroyed and the stones were eventually removed and used to construct nearby Carreghofa Hall. Very little remains of the castle today.
