Osuna’s Roman Theatre is from the Genetiua Iulia colony. It is located in the southeastern part of the crossing between the Cañada Real de Marchena to Estepa and Vereda de Santa Mónica. This site has traditionally produced main findings from the Roman era. It seems that researchers’ results coincided when recreating the centre of the colony around the crossing of both livestock routes given the abundant findings on this site. They include bronze boards with the colony’s founding law inscribed on them.
