When the Piazzo Tasso was built in 1866, the crevice was closed off from the sea and the humidity inside the gorge rose sharply. Right in the middle of the bustling coastal town of Sorrento is a deep, narrow gorge known as the Vallone dei Mulini, the #Valley of the Mills 12, named for the flour and saw mills that once ran inside the rocky cleft. Soon, the stepped dwellings will be entirely subsumed by nature – as if they had never been there at all. Now, its walls and streets are viridescent with overgrowth where once there were bricks and mortar, walls are adorned with climbing vines. It's no wonder, then, that its isolation was one of the prime factors leading to the abandonment of the village in the 1990s. Each is an arduous, hours-long journey from the mainland. It is tethered to its neighbour, the equally small island of Gouqi, by a bridge, but the only way to get to either is by private boat, or by bus and then ferry.

1 The island of Shengshan is on the furthermost curling edge of an archipelago of islands in the East China Sea, about 65 kilometres (40 miles) from the mainland coastal city of Shanghai. In fact, it has taken nature fewer than thirty years for plants to reclaim the tiny Chinese fishing village of Houtouwan.

These vividly overgrown walls look as if they were abandoned to the elements centuries ago.
