The Y-shaped UNESCO headquarters, built in 1958, is home to a swarm of international diplomats. It's worth visiting for the sculptures and paintings - by Picasso, Arp, Giacometti, Moore, Calder and Miró - and for the Japanese garden, with its contemplation cylinder by minimalist architect Tadao Ando. Tours need to be reserved three months in advance.
