During 2013, research in the ancient city of Dimal was focused on two sectors: that of the Acropolis of the city and the western gate of the fortification system. This year’s excavations aimed at understanding the situation in the eastern part of the city’s agora. Across the entire width of this area, a square grid was positioned, with 4 × 4 m squares (A1, B1, etc.), where a total of 14 trenches were opened. While two other trenches, obliged by the shape of the terrain had different sizes. At the end of the excavation, it was proved that in this space we have constructions that date back to the period of late antiquity. As for the earliest layers, they were found only in one of the trenches. From the preliminary analysis of the archaeological material, it seems that they date to the first phase of the expansion of the Acropolis, exactly in the IV – III B. C. In the excavation areas A8, A9 and B8, the later stages of the area’s development, precisely from the century II – I B. C. were encountered. A construction which is unusual in several ways was also discovered, It apparently must have consisted of only one room with dimensions of 6 × 4 m and an L – shaped wall closes the building to the west, while on the east side the building rests on the natural rock. In front of this wall, the remains of a layer of stones and bricks were encountered, which covers the natural rock platform (0.5 m x 1.5 m). During a second phase, the structure was equipped with a second room, trapezoidal in shape (5 × 4 m), with an entrance from the west. The function of this construction is unclear. In the rest of the sector of the upper agora, a later construction was discovered, consisting of several rooms. The state of preservation of the structures makes it difficult to determine whether these rooms belong to a single large construction, or whether we are dealing with several smaller constructions. The second sector where archaeological research was concentrated during 2013 was the western gate. During the excavations in this sector, the remains of the tower of the gate and a room of the gate were brought to light. The latter, due to its location in a depression of the terrain, was covered by several meters of sediments, belonging to the post-antique layers.
Based on the form of construction, the tower presents the same characteristics as its counterpart, the southern tower. The floor plan is approximately square, measuring 8.3 m × 6.7 m. The outer walls have a thickness of up to 2.1 m: we are dealing with large stone blocks, three rows of which are preserved in the southeast corner. Above the rows of stone blocks is the construction of baked brick walls (45 cm x 24 cm x 8 cm). Traces of this technique are preserved in the western part and in the southeast corner of the tower.
