Urban archaelogy is a fascinating genre – a fascination exacerbated for Britons as we can hardly imagine so many vast structures existing unknown and unloved in Britain’s tightly packed urban fabric. But exist they do - the UK is apparently full of the unknown. Cane Hill Hospital in Coulsdon, South London, is an example of a homegrown abandoned asylum - this aerial photo gives you some indication of the scale. At Spring Hill in Wiltshire there is a citadel of similar size - only underground. The 2,000,000 square foot construction, built during World War 2, contains these remarkable murals decorating the canteen.

A few more links. Dead Malls is concerned with a more mundane element of the built environment, but no less interesting when left to the elements. The Urban Exploration webring has links to sites all over the world, while this site has details on closed stations along Paris's metro (see the forthcoming things 16 for a piece on Moscow's hidden metro lines). Ghost Towns are also popular on-line destinations, though few sites are as slick as the Ghost Town Gallery, a semi-professional travelogue across the abandoned communities of the old west.
