Saint Archbishop Sava (1175 - 1235), originally born prince Rastko Nemanjić, son of the ruler and founder of the Serbian medieval state Stefan Nemanja and brother of the first Serbian king, was the first Archbishop of Serbia (1219-1233), the most important saint in the Serbian Orthodox Church, and an important cultural and political worker of his time. The temple stands on the site where the remains of Saint Sava were burned by the Turks in 1595.
Saint Sava is the founder of the independent Serbian Orthodox Church and is celebrated as the patron saint of education and medicine. Today, January 27th, schools all over Serbia celebrate Saint Sava's Day by singing songs and reciting poems in his honor.
