Despite this purpose, the area continued to be threatened, with Edward I of England spending three days in Trecastle quelling a revolt in 1295.

The fortification still exists at the east end of the village and the motte is 21 feet (6.4 m) high; the largest of its type in the National Park.

In the 19th century Trecastle had eight annual fairs, its own gasworks, two schools, a grain mill, two smithies, 16 shops and numerous pubs.
