I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
King Alfreds Tower
King Alfred's Tower is a folly in Somerset, England, on the edge of the border with Wiltshire, on the Stourhead estate. The tower stands on Kingsettle Hill and belongs to the National Trust. This is National Trust so TOAL is not permitted within the towers grounds but can be done from nearby.
Parking on site is free and exploring the wooded grounds is must.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 20/11/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
