Tump Terrett Castle - Added to Castles and Fortifications in Monmouthshire, Wales

I have just added this to the map of places to fly your drone at Drone Scene:

Tump Terrett Castle, also known as Trellech Castle, is a medieval motte-and bailey site in the village of Trellech, south Wales.

The castle consists of a large, steep sided earthen mound with a flat summit about 14 metres across, surrounded by traces of a defensive ditch—best preserved on the northern side.

First recorded before 1231, it likely served as an administrative centre within the Norman lordship of Usk and stood beside a thriving planned town established by the de Clare family. By the late 13th century, Trellech had grown into one of the largest towns in Wales, larger even than Chepstow, though it later declined.

Archaeological surveys indicate structural remains in the former bailey area, Today, the site survives as a scheduled monument and an important example of early Norman fortification.

Just a short flight away are Harold's Stones -a striking trio of Bronze Age standing stones forming a 12 metre alignment, each one leaning at a different angle—likely due to subsidence or centuries of disturbance rather than intentional design.

The tallest stands over 4 metres high, with the others measuring roughly 3.5 and 3 metres. Their original purpose is unknown, though they may once have been part of a larger ritual landscape. The stones were significant enough to influence the village’s name—Trellech, often interpreted as “village of the three stones".

For those interested in ancient historic churches, The Church of St Nicholas is the local parish church with its origins in the 14th century. The historical and architectural evidence suggests that it was constructed largely in a single building period c.1300. It’s a Grade 1 listed building and nice to view from the air
