I have just added this to the map of places to fly your drone at Drone Scene:
The long barrow near Portskewett is called Heston Brake. It's a Neolithic chambered tomb located in a field on a hill overlooking the Severn Estuary. The site is also known as a "dolmen" or "cairn".
Heston Brake is situated in a field near Portskewett, specifically on the brow of a hill overlooking the Severn Estuary. It's about half a mile northeast of Portskewett
The entrance to the barrow is marked by a small group of puddingstones. In 1888, the chamber of the barrow was excavated and human skeletons, cattle bones, and pottery were found.
The site is on private land but can be accessed via a public footpath. The footpath is reached by a kissing gate about 150 meters from the main road towards Leechpool.
Be wary of lots of overhead cables criss-crossing the site
The barrow is over 4,000 years old, dating back to the Neolithic period. It is considered a significant site and is sometimes mentioned alongside other dolmens like Garn Llwyd and Gwern-y-Clepp
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 21/07/2025. It remains the responsibility of any pilot to check for any changes before flying at the same location. Landowner permission may be required before taking off.
