The monastery's Upper Church was built within two natural cave cavities in the rock face.
Saint Basil of Ostrog, the monastery's founder, died in the cave cell now serving as a small chapel.
Many of the frescoes in the Upper Monastery were created by master Radul in 1667.
The monastery is located at an altitude of approximately 900 meters above the Zeta River valley.
Pilgrims often walk the path between the Lower and Upper monasteries barefoot as a form of devotion.
The relics of Saint Basil are kept in a wooden coffin in the Church of the Presentation.
The monastery has survived multiple fires and historical conflicts without losing the core structure of its cliffside cave chambers.
Water collected from the rock near the monastery is widely regarded by visitors as possessing miraculous properties.
Ostrog Monastery is a 17th-century Serbian Orthodox site carved directly into a nearly vertical cliff face in the Ostroška Greda mountains of Montenegro. Founded by Metropolitan Bishop Vasilije of Zahumlje in 1665, the monastery comprises the Upper and Lower sections connected by a winding mountain road. The Upper Monastery houses the Church of the Presentation and the Church of the Holy Cross, both containing frescoes painted directly onto the stone walls. It serves as the primary pilgrimage site for the saint's relics, which are believed by the faithful to possess healing properties. The architecture is a literal integration of a natural cave system and human-built stone masonry. The site is split into two complexes: the Lower Monastery, which includes the Church of the Holy Trinity, and the Upper Monastery, accessible via stairs or a steep path. It is currently an active monastic community. The site remains one of the most visited Orthodox religious centers in the Balkans.
Wear comfortable, sturdy footwear as the walk to the Upper Monastery involves steep inclines and uneven stone steps.
Bring a headscarf (for women) and ensure shoulders and knees are covered, as this is a strict requirement for entry into the inner shrines.
Visit on a weekday to avoid the significantly higher crowds typical of weekends and major religious holidays.
Do not attempt to photograph the interior of the shrines or the relics, as this is strictly prohibited.
The complex is open year-round, though snow can make the mountain roads difficult to navigate during deep winter.
Strict dress code: long pants for men, skirts or dresses covering knees for women, and covered shoulders for all. Maintain silence, as this is a functional monastery.
