North of the acropolis on Manuzza Hill, the modern street traces the border of an area in the form of a massive trapezoid in which the ancient agora was presumably located. The whole area was occupied by habitation on the Hippodamian plan (reconstructed by means of aerial photography), on a slightly different orientation from the acropolis, with elongated insulae of 190 x 32 metres oriented north-south, which were originally surrounded by a defensive wall. There have not been systematic excavations in the area, but there have been some sondages, which have confirmed that the area was inhabited from the foundation of Selinus (seventh century BC0 and therefore was not a later expansion of the city.
