I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
TOAL was from the end of the track running South of the A4, by the cattle grid, just before the start of NT land.
Built into the hill about 100 BC, the hillfort (sometimes known as Oldbury Camp) was a defensive settlement. Covering an area of 123 acres, its defences included over 2 miles of ramparts (banks or walls) and palisades (high wooden fences with no space between posts).
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 09/01/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
