This is the Dragon’s Eye stone mine in the UK
This peculiar stone mine, which looks like something out of an Indiana Jones movie, was discovered at the Hall of Giants stone mine in Lancashire, UK. Apparently, the surface is actually flat rather than curved. The underground adventurers who found this mine in Northern England took the picture with a fisheye lens.
A collapsed mine roof exposed different colored sediments, resulting in the formation of the dragon’s eye. Nowadays, the cave is closely guarded by residents and explorers who want to keep the exact location hidden from the rest of the world. Everyone is probably waiting for this stone to blink.
