I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Ewloe Castle just of the A55 onto the B5125 there is a small parking spot near to the pathway to the castle it is also near to the Boarding Kennels, short walk into the wooded area & the castle will be on your left, the castle is lower down in the land than the land you walk in on which make it different from all other castle I know of
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 14/06/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
