The Northern part of the Stadium has a curved section called sfendona. The seats are arranged in tiers of 14 rows, crossed by staired aisles. The seats are raised to 1.80 metres by a podium. They surround the track to the East, West and to the North. The track itself was three-layered, the finishing one being mortar.The main entrance called Propylaea was to the South and was designed for the athletes to enter.
A covered passage was found under the sfendona. It turned out to be an ancient vaulted covered street. The floor of this street is paved with syenite blocks covering a stone masonry canal.
