I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Hartshill Castle is a ruined castle in the village of Hartshill on the outskirts of Nuneaton, Warwickshire. It is on Historic England's Heritage at Risk Register.
The Castle Ruins are located on Hartshill Hayes Country Park, which comes under Warwickshire County Councils Country Parks. Warwickshire County Council have a blanket no drone policy in their country parks.
However, the castle ruins are easily visible from Castle Road and there is a view point installed looking over the ruins. The viewpoint has trees around it so I would recommend taking off from the footpath, getting a good height and then flying over closer if you need too.
Good location if you're into photography of ruin sites, but other than that there is not much else exciting here.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 22/08/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
