View from the Church of the Dormition towards the old city of Jerusalem

You can see the wall surrounding the Old City and clearly the Dome of the Rock from here.

The hill of Mount Zion, the highest point in ancient Jerusalem, is dominated by the Church of the Dormition. The location is identified in Christian tradition as the place where the Virgin Mary died — or “fell asleep”, as the name suggests.
The fortress-like building, with a conical roof and four corner towers, stands south of the Old City’s Zion Gate. Nearby soars the bell tower of the Hagia Maria Sion Abbey (formerly the Abbey of the Dormition), a Benedictine monastery.

During the Byzantine period, the Church of Hagia Sion (Holy Zion), one of the three earliest churches in Jerusalem, stood on this site. Built by the Emperor Constantine, it was regarded as the Mother of all Churches. In AD 614 it was destroyed by the Persians.
