I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Dedicated car park. Cross road and follow path along the river until you reach a crossing. Follow final paths to the monument. Easy 5-10 minute walk. Early morning is best to beat the crowds.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 16/09/2020. It remains the responsibility of any pilot to check for any changes before flying at the same location.
