The Treasure Cave centers on the famous Tehran Museum of Contemporary Art, which is widely considered to be the region’s most important store of modern Western art: Picasso, Chagall, Warhol, Bacon and possible the best Jackson Pollock outside of the United States. However after the revolution, its collection has been little seen, and the building became a memorial to art commemorating the martyrs of the 1979 revolution and Iran-Iraq War.
