The South Basilica was built over the area of the Athena and Apollo temples in the 5th century AD. It has three naves and a large atrium. It has narthexes (corridors) on the sides and a central apses with a synthronon (bench for priests in the apsis part) in the middle. On the both sides of the apsis are pastophorium rooms (rooms for the priests, with to the left of the apsis usually the sacrificial gifts, to the right the liturgical gear). At the southeast corner a central planned building. The basilica may well have been a martyrion (grave of a saint). Destroyed in the 7th century its parts were used to built a smaller church in the centre.
