Basilica of the Annunciation, Nazareth, the first church was established during the Byzantine times, probably around the year 427. It was built by Jerusalem’s Deacon (one of the 3 positions in the Christian clergy, next to the priest and the bishop), who was called Conon, which can be seen from the writing “Conon” on the mosaic floor, close to the cave.
The church was built as a large central hall, with a small monastery to the south.
