History

The Monastery was founded in the early 17th century by Vasilije Jovanović, better known as St.Basil of Ostrog, the Metropolitan of Herzegovina, and is first mentioned on a geographical map of[Montenegro from 1640. Vasilije died there in 1671 and some years later he was glorified. His body is enshrined in a reliquary kept in the cave-church dedicated to the Presentation of the Theotokos.
The present-day look was given to the Monastery in 1923–1926, after a fire which had destroyed the major part of the complex. The two little cave-churches were spared and they are the key areas of the monument. The frescoes in the Church of the Presentation were created towards the end of the 17th century. The other church, dedicated to the Holy Cross, is placed within a cave on the upper level of the monastery and was painted by master Radul, who successfully coped with the natural shapes of the cave and laid the frescoes immediately on the surface of the rock and the south wall. Around the church are monastic residences.
During World War II, German forces looted gold from the monastery. It would also become a place of refuge for a detachment of Chetniks led by Blažo Đukanović and Bajo Stanišić took refuge at Ostrog up to October 18, 1943, when Yugoslav Partisans promised the Chetniks that their lives would be spared if they surrendered. Đukanović and 23 Chetniks peacefully surrendered, expecting to be spared, but were all killed by the Partisans at Ostrog. Stanišić and three members of his extended family initially did not surrender,
