The opening named Dereboyu 2 (downstream2) lies, roughly 200-250 meters southwest of Maritime Villa sector, roughly 200 meters northwest of over the road opening which was worked on between 2001-2004, roughly 15 meters southeast of Fortification/Rampart sector and 45-50 meters east of Karakazan (Kundakçınar) river.
During the drilling works for stratification of Antandros city, first architectural findings were encountered right beneath the agricultural soil level. The most important findings group of the downstream 2 opening area were found at 10.30-10.20 meters level of the opening and consisted of a total of 150 hydrias of which 55 were intact or close. This group of ceramics dated as 3rd Century BC, were not found at a specific level and it was not possible to associate them with surrounding architecture. These small hydrias which are usually found in sacred Demeter areas of cities like Priene, Miletos, Pergamon and Thasos are related with the cult of Demeter and Mother Goddess. Although the existence of such a great number of small hydrias indicates the existence of a sacred area, no related architectural structure was encountered yet.
Right under the level where the small hydrias were, walls started to be unearthed, and then they turned into a room with four wall structures. In this area a number of 4th century BC ceramics were found. But, no flooring or in-situ material was seen there. In the lower levels of the area, ceramics from 7th and 6th centuries BC were retrieved and in the lowest level big stones were started to be seen. As these stones seemed to form a platform, it was considered that they could be related with a defensive wall.
The works in the upper levels of the downstream 2 opening that was widened during 2007 season, revealed the existence of a Late Roman period architecture manifesting itself with water pipe, manhole and walls. An interesting stone block was found, used as a part of the wall right behind the manhole. The stone block had the images of a tripod caldron, an arrow and a quiver forming the attributes of Apollo. Such leads the thought that this block stone might have been taken from a near-by Apollo sacred convent.
Another important finding is a 3 meters high 35 cm thick block unearthed on the north of the opening. The block continues till the wall at the north of the opening. Although the relation between the block and the architecture has not been found yet, it is presumed to be a stone used in a sizable area of Hellenistic period. However, its quality has not been understood until now as it remained underneath the late Roman architecture that was built upon it.
