This is the site of Ruperra Hill Fort, near Caerphilly (yes famous cheese).
It has been lived on for thousands of years with fantastic views of the surrounding countryside. This map was taken with a DJI inspire consisting of only 12 frames. The wall you can see is not that old, but the groundworks underneath and surrounding are many hundreds of years old.
Boat Floated scale 1-10 i'll give it a 5, but the views were incredible which i will give an 8. dont forget to push it around the screen.
