Ostrog Monastery is one of the most revered religious sites in all of the former Yugoslav states. It’s visited by up to a million tourists and pilgrims every year. It’s also revered and visited by Orthodox Christians, Roman Catholics and Muslims. From afar, Ostrog looks like it defies gravity. It’s built right into a sheer cliff face way above the plains below. You can see the white of the building shining like a beacon against the dark rock from miles away.As soon as you get off the bus, you'll be left in awe of the spectacular natural landscapes surrounding you and by the sheer size of Ostrog Monastery.
