The video illustrates the different phases of the Church of the Holy Sepulcher moving backwards in time from the Crusades until Crucifixion. Here is the information from the site:
A journey back in time to tell the story of the Basilica of the Holy Sepulchre in Jerusalem, the site defined in many Christian traditions as “the Centre of the World”. This is the gift by ATS pro Terra Sancta to all the friends and the supporters of the Holy Land. Divided in chapters, the video by Mrs. Raffaella Zardoni for ATS pro Terra Sancta presents a 3D reconstruction of the basilica at different times, back to the stone cave which saw the burial and resurrection of Jesus Christ. Our being here, our commitment for this land and our deep desire to help its living stones start and gather meaning from here.
