I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
The park opposite Newark Castle is often very quite and the council has no byelaws or drone restrictions in place. There is a car park adjacent to the green space.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 24/07/2020. It remains the responsibility of any pilot to check for any changes before flying at the same location.
