US Den of Espionage
The former US embassy was the focal point of the 1979 revolution, when it was stormed by students who then held 52 diplomats hostage for 444 days. Today the compound is occupied by the Student Basij Organisation dedicated to defending the revolution. It's a fascinating place to visit: the front grounds (now called the 'Museum Garden of Anti Arrogance') are plastered with colourful anti-Western propaganda posters. Part of the chancery is a museum, highlighting the spying which went on there.
