William erected a Monastery at Montacute Mountain, and endowed it with the borough and market of Montacute. An ancient record written about 1538 states that, "within the ruins of the castle at Montacute is now a mean house for a farmer, the town has a poor market and is builded of stone as commonly all towns thereabout be." But little is known with regard to this William Montacute, except that one author says that he was an only son, and that he took care of the estate left him by his father, and died leaving it entirely to an only son, Richard of Montacute.
