As the President, Tito had access to extensive (state-owned) property associated with the office, and maintained a lavish lifestyle. In Belgrade he resided in the official residence, the Beli dvor, and maintained a separate private home. The Brijuni islands were the site of the State Summer Residence from 1949 on. The pavilion was designed by Jože Plečnik, and included a zoo. Close to 100 foreign heads of state were to visit Tito at the island residence, along with film stars such as Elizabeth Taylor, Richard Burton, Sophia Loren, Carlo Ponti, and Gina Lollobrigida.
