A visit to Tito's mausoleum is obligatory. Also on display are thousands of elaborate relay batons presented to him by young 'Pioneers', plus gifts from political leaders and the voguish set of the era. It's attached to the fascinating Museum of Yugoslav History. Take trolleybus 40 or 41 at the south end of Parliament on Kneza Miloša. It's the second stop after turning into Bul Mira: ask the driver to let you out at Kuća Cveća.
