The Sisojevac Monastery, located at the source of the Crnica River near Ćuprije and close to the Ravanica Monastery, has a rich history. Its origins are linked to the priest Sisoj, mentioned in a charter by Princess Milica from 1398 when she was known as nun Evgenija. It is believed that the monastery church of the Transfiguration was built during this time. However, some opinions suggest that the church is much older and that Sisoj only renovated it. Additionally, it is thought that the church was originally constructed as a manor house by lord Crep Vukoslavić and later became a monastery after the arrival of monk Sisoj.
