The church was built in the 5th century AD and was built on the temple of Isis (the god of motherhood in Greek mythology). There is not only one church, there are seven churches in the beginning, and the locals also call them the seven churches, but I can't see how many there are. This is a huge religious complex that combines Roman-era style with fine art of carving. Each church has a different style, with a rich corridor and courtyard, and it is interesting to not have many tourists.
