The mosaic decoration of the Church of the Annunciation in Nazareth, which was one of the great Constantinian basilicas of the Holy Land, was totally destroyed during the centuries together with much of the basilica. Archeological evidences prove that prior to the mid-4th century another small church stood on the site. A mosaic inscription referring to Deacon Conon survived of this building. The existence of a large Byzantine church on the site of the present-day Sisters of Nazareth convent was proven in 2006-2007. This church was architecturally complex and elaborately decorated, it was floored with polychrome mosaic (of which only very scant remains survived) and also had polychrome wall mosaics. Further mosaic-floored Byzantine buildings were located to the south of the church. This evidence indicates that Byzantine Nazareth contained two large churches dominating its centre, with other mosaic-floored and colonnaded masonry structures around them. As such the town had to be an important Byzantine pilgrimage centre. On the top of nearby Mount Tabor which was venerated as the place of the Transfiguration of Christ another great church was built before 422. A small portion of its mosaic floor survived.
