I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
This castle is located in a public park, be mindful of the local dog walkers.
There are a few parking spaces on a nearby street but they fill up fast.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 18/02/2024. It remains the responsibility of any pilot to check for any changes before flying at the same location.
