A new Tate-sponsored website called the Gallery of Lost Art has been set up to showcase modern and contemporary pieces that have been destroyed or lost, stolen or erased. The Gallery is currently showing 21 works of art in the form of dossiers with interviews, archival photographs and essays. Among them are Daniel Buren's 1971 installation for the Guggenheim's rotunda, Paul Thek's Tomb which a storage company is said to have discarded in the 80s, and Rachel Whiteread's monumental public work House (1993), which was destroyed as the artist intended. You can visit the Lost Art site here.
