One of the sights of London, if you like urban decay, and disused power stations. It's near Battersea Bridge on the side of the Thames. A large, monolithic building with two white towers, designed by Sir Giles Gilbert Scott and completed in 1933, it's got that typical 1920s/30s Art Deco style. Pink Floyd used a picture of it on the front cover of Animals, with a giant pink floating pig tethered to it.

Over the years there have been various ideas for using the building, but none have actually happened. It's currently the subject of a controversy over plans for a new leisure centre.

thanks to wunderhorn1 for remembering the pig.
