I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
TOAL and parking is about 10m from the Long Barrow, on the track that runs South of Pewsey Road.
The Long Barrow at All Cannings is the first Long Barrow to be built for over 5000 years. It is a working columbarium, a place to leave cremated remains in urns on shelves in niches.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 16/01/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
