Property hunters are being given a "rare opportunity" to live in a cave.
Rock Cottage, which is hewn out of a sandstone cliff near Wolverley, Worcestershire, was last occupied in the late 1940s.

Given a guide price of £25,000, it comes complete with three adjoining caves and has generated more than 50 requests for viewings.
Auctioneer Daniel Lovatt, of Halls Estate Agents, Kidderminster, said the sale offered a "unique opportunity".
He added: "How many people can say they own a cave home?"
The cottage in Sladd Lane has no electricity or water supply but boasts a front door, windows and fireplaces, as well as a pantry, sitting room and a bedroom.
It also includes nearly five acres of mixed woodland and garden land and is being auctioned on Wednesday following the death of the previous owner.
