In 2004 work continued in trench Z and a new trench was opened linking this with trench T, which had been excavated in the 90s. The new area, denominated J/K, was situated in correspondence with trench T to the south-east of the temenos(?). The removal of a rubble fill datable to the 1st century B.C. revealed the razing of a wall which seemed to close the room that came to light. The occupation level in the room had a sandy matrix and contained 3rd-2nd century B.C. material. In contrast to the preceding campaigns in the north-west part of the enclosure (trench T), where numerous bothroi and votive pits had come to light, no similar elements were found. Thus the site must have been used as some sort of vestibule with respect to the area destined for cult practices. Below this level was the make up for a pavement and then that for the actual construction of the building. (MiBAC)
