I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Rothley Castle is a Grade II* Listed 18th century folly by Daniel Garret for Sir Walter Blackett.
There is free parking at W3W: ///blackmail.certified.uncle and a public footpath starting at ///stroke.brambles.icon (wellies are recommended…)
At the time of posting, the trees adjacent to the parking place have been cleared. This provides a clear line of sight from the car park to the castle, very convenient if you can still see your drone from about 1km away…
The other end of the public footpath is at the other side of the castle W3W: ///fast.remainder.lizard
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 02/03/2023. It remains the responsibility of any pilot to check for any changes before flying at the same location.
