Ephesus Baptistry of the Church of St. John the Theologian



This octagonal building stands next to the Church of St. the Theologian in Selçuk near Ephesus. In the center of the building is a baptismal pool. From its size, it is clear that adult baptism was practiced here. Two sets of steps led down to the middle of the pool and water was guided in through pipes that were laid under the floor.
