Within Tupgill Park in North Yorkshire, England, is a garden full of grottoes, tunnels and mazes that bills itself as the strangest place in the world. 

Built during the ’80s and ’90s, the Forbidden Corner has faces in its grotto walls, arms sticking out from beneath building eaves, and a stone knight in armor holding his own severed leg aloft. A giant ax sticks out of the ground and a horse’s head peers over one of the stone walls. Nothing quite makes sense, and there is no central motif beyond oddness.

Though initially intended as a private garden, the Forbidden Corner opened to all in in 1994 in response to demands from the curious public. Visitors do not receive a map, but are instead given a checklist of things to look out for, including a tree spirit, a temple leading to the underworld, and a giant skull.

The Forbidden Corner opens for the 2015 season on March 28. Admission is by prepurchased ticket only.
