The Church of Saint Sava is a Serbian Orthodox church located in the Serbian capital city of Belgrade. The church is one of the largest Orthodox churches in the world and is dedicated to Saint Sava, the founder of the Serbian Orthodox Church and an important figure in Serbian history.

Construction of the church began in 1935, but was interrupted by World War II and was not completed until 1989. The church's design is based on the medieval Serbian Orthodox monasteries and churches, particularly the Mileseva Monastery in western Serbia. The church features a central dome, four smaller domes, and two bell towers.

The interior of the church is decorated with frescoes and mosaics depicting scenes from the life of Saint Sava, as well as other important figures in Serbian history and Orthodox Christianity. The church also houses relics of Saint Sava, including his right hand.

The church is located on the Vracar plateau, one of the highest points in Belgrade, and is a prominent landmark in the city. It is also an important site for Serbian Orthodox Christians and attracts many visitors and pilgrims each year.
