Silvio Berlusconi's summer retreat on Sardinia's exclusive Costa Smeralda, which gained notoriety for parties with topless models, features an underground cave, complete with an emergency escape exit to the sea.
The existence of the cave at the former Italian prime minister's Villa Certosa estate had been rumoured for years but the first photographs of it emerged on Friday.
They were obtained by Antonello Zappadu, an Italian photographer who made his name in 2009 by taking long-lens pictures of scantily-clad showgirls at Mr Berlusconi's residence.
