I have just added this to the map of places to fly your drone at Drone Scene:
Northumberlandia (the "Lady of the North") is a huge land art sculpture in the shape of a reclining female figure, which was completed in 2012, near Cramlington, Northumberland, northern England. It is in the care of Northumberland Wildlife Trust.

Made of 1.5 million tonnes of overburden from the neighbouring Shotton Surface Mine, it is 34 metres (112 feet) high and 400 metres (1,300 feet) long, set in a 19 hectares (47 acres) public park. Its creators claim that it is the largest land sculpture in female form in the world.
When constructed, it was intended to be a major tourist attraction, with the developers hoping that it would attract an additional 200,000 visitors a year to Northumberland.[3] It was officially opened by Anne, Princess Royal on 29 August 2012.[4] A day-long Community Opening Event on 20 October 2012 marked the park becoming fully open to the public.
You will have to approach the visitors centre for permission to fly there but it is possible.
The originator declared that this location was inside a flight restriction zone at the time of being flown. Permission to fly was obtained from Northumberlandia visitors centre. It remains the responsibility of any pilot to check for any changes before flying at the same location. Landowner permission may be required before taking off.
