The monastery is located on the site of a former 14th-century hermitage that was later expanded by Neagoe Basarab.
The island on which the monastery sits was historically known as the island of Arutela.
It is one of the few surviving monastic sites in Romania located entirely on an island within a riverbed.
The monastery was significantly damaged by floods in the 19th century, leading to its subsequent reconstruction.
Some of the original 16th-century frescoes were lost during historical renovation efforts.
Ostrov Monastery is a historic Eastern Orthodox convent situated on an island in the Olt River, accessible via a small concrete bridge. Built between 1520 and 1521, it stands as the first monastery in Wallachia constructed on an island. The monastery was founded by Neagoe Basarab and his wife, Despina, as a votive offering. The current church is dedicated to the Descent of the Holy Spirit and the Birth of the Virgin Mary. It underwent significant restoration in the 19th century, which modified much of its original interior appearance. The site features a notable collection of religious icons and historical embroidery pieces. The grounds are characterized by an enclosed courtyard with manicured gardens and tall stone walls. It remains a functioning monastic site today, maintained by a small community of nuns.
