Milentija Monastery, Medieval monastery in Brus, Serbia.

Milentija Monastery is a ruined medieval monastery near the village of Milentija in the municipality of Brus, close to the Koznik fortress. Its church, dedicated to St. Stephen, has a compact triconch plan with semicircular apses and a dome over the nave, and is 17.5 meters long. The walls stand about 2 meters high; the exterior was decorated with carved stone, parts of which are now in the National Museums in Belgrade and Kruševac.

Founded around 1430 during the reign of Serbian Despot Stefan and Đurađ, this monastery was potentially established by nobleman Radič Postupović. This founding period marked a significant moment when monasteries served as important centers of faith and culture in the region.

The name Milentija comes from the village where the monastery stands. Among the surviving stonework, a large rosette bears a stylized ox head, although Morava-style rosettes almost always show geometric or plant motifs. A fully reconstructed rosette and several archivolts are displayed in the permanent exhibition of the National Museum in Belgrade.

The site is best reached on foot, and visitors should be prepared for rural paths and terrain that may vary with seasons. It is best to wear sturdy footwear and approach the remains respectfully, as this is a protected cultural monument.

In a building about twenty metres west of the church, archaeologists found a niche holding a child's skeleton laid on its back as in a normal burial, the child no older than seven. The find is taken as evidence of human sacrifice at construction, a practice otherwise recorded in this region only in folk poetry such as the Building of Skadar.
