In the 2000 research began in the area outside the precinct wall of the former city, located between the Great Gate and the Great Tower, and had the purpose of observing the early Roman city – possibly the Hellenistic city, but also to uncover, from a tourist’s point of view, a part of the central part of the city. The area underwent many interventions after the building of the precinct wall (238 AD), and especially from 1914 onwards, with the beginning of the archaeological excavations at Histria. The 2000–2003 research works brought to light three buildings and a number of complexes, most of them dated before 238 AD. This year’s objectives were the research of a number of complexes that were discovered in the previous years, some aspects of building no. 1, as well as the clarification of certain stratigraphical issues. This year’s research was focused on the area between the precinct wall, the tower and the bastion to the right of the Great Gate, in order to obtain information concerning the north and west limits of the building. The research here provided information only on the building limit in its third phase and maybe later on, when the building changes its planimetry. Moreover, the whole layout of the building in this period seems to be adapted to an orientation defined by a new street system that throws the Hellenistic one into disuse. Future research here, as well as inside the city, will clarify all the details of these phases. Research in cassette A has also allowed us to observe some construction details of the precinct wall. Thus, under the tower there are three big, very good quality marble column trunks, and the plinth (built in a negligent manner, out of shales and limestones bound with earth) links the tower to the bastion.
