The rescue excavations of 2009 undertaken at “Demokracia” square, near by the street “P. Meksi”, revealed important data about the ancient city of Dyrrah. The excavation uncovered 7 archaeological layers. Underneath a layer of tiles and bricks fragments of the Late Roman period, a dark brown humus layer was found, with a thickness varying from 0, 14 to 0, 34m. Beneath it, demolishing materials were uncovered, including bricks, pottery, stones and traces of mortar, which seems to arrive from a collapsed wall made of bricks, stones and mortar. A wall of 0, 65 m thick and 0, 80 m high was uncovered in the lower layer. It was built with stones of various dimensions bonded with ample amounts of mortar. The wall is thought to date to the Late Roman period. In addition, another wall made of made of bricks, tiles and lime mortar (1, 10 m thick, 0, 90 m high and 1 m long) was revealed during this excavations. Some timber holes (0, 29 × 0, 33 m and 0, 17 × 0, 24 m) were visible in the entire length of this wall. Based on the construction technique and the materials revealed, the wall dates to the Late Roman period. Next to it, an earth deposit containing pottery fragments of the Late Roman period and Roman wall frescos was discovered. This latter were revealed at the lowest stratigraphic layer of the excavations. Remains of a Late Roman sewer made of tiles and mortar were also uncovered. One of its sides (4 m long) runs toward the northeast-southwest, whiles the other (3 m) on the southeast-northwest direction. Its depth was 0, 22 m at the opening point of the flow, and reaches up to 0, 36 m at its end point. Marble slabs of various shapes were used as a covering layer. It functioned perhaps as a drainage system of the habitation area. The discovery of this structure is indeed highly important for understanding the urban system of the ancient quarter during the Roman and Late Roman periods.
