The Crusader Holy Sepulchre Church. The form of the church as we know it today is that given it in the 12th century by the Crusaders. The rotunda encloses the tomb of Jesus as before, but now for the first time the rock of Golgotha is enclosed within the church. In the area of the porticoed Holy Garden, the Crusaders built a basilica with a nave, a transept and a high altar at its eastern end.
In the area of the subterranean cisterns on the eastern end of the complex, three chapels were constructed: the chapels of St. Helena, of the Finding of the True Cross and of St. Vartan. Signs of an ancient quarry may be seen in St. Vartan’s chapel.
