I have just added this to the map of places to fly your drone at Drone Scene:
Hardwell Castle or Hardwell Camp is an Iron Age valley fort near to Compton Beauchamp in Oxfordshire (previously Berkshire).
The earthwork is in reasonable condition with visible ramparts and ditches among the wood that covers large parts of it. From the Western and Eastern side the hillfort is protected by natural ravines, while the earthwork is particularly strong from the South. The site has never been excavated
It lies halfway down the scarp slope of the White Horse Hills and is tucked away in a curve, invisible from most angles. The site is surrounded by a double vallum (earth rampart) 140 by 180 feet (40 by 50 m) in dimension.
It has been a Scheduled Monument since 1958.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 25/07/2025. 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.
