Purely decorative follies do not spring up like trees, so here is a functional folly which has done just that – the Okinawa treehouse which is poised in a banyan tree (or maybe it is a gajumaru tree). Whatever. The tree is in fact concrete.

Back in the late nineteenth century the French were making trees out of cement and a good example of has survived at Oakworth Park in Yorkshire. But I have not seen such a bizarre and impressive modern version as this before.

This treehouse is a restaurant, serving Asian food. It is located on Highway 58 at the entrance to Onoyama Park in southern Japan where it overlooks the ocean. Visitors ascend via a lift inside the trunk.
