The Church of Saint Sava is a Serbian Orthodox church which sits on the Vračar plateau in Belgrade, Serbia. It was planned as the bishopric seat and main cathedral of the Serbian Orthodox Church. The church is dedicated to Saint Sava, the founder of the Serbian Orthodox Church and an important figure in medieval Serbia. It is built on the presumed location of St. Sava's grave. It is the largest Orthodox church in Serbia, one of the largest Eastern Orthodox churches and it ranks among the largest churches in the world. It is the most recognisable building in Belgrade and a landmark, as its dominating dome resembles that of the Hagia Sophia, after which it had been modelled.
