In 2018, excavations at the stronghold in Pasym in the Szczytno district continued (Figure 1). They were mainly concentrated on the area within the stronghold. Three excavations were carried out (Figure 2). Trench 1 (15 × 5 m) was situated in the western part on the extension south of Trench 1 from 2017. Excavation 2 (5 × 5 m) was located in the north-west part of the stronghold, on the slope descending towards the lake. Trench 3 (2 × 2 m) was located at the foot of the stronghold on the lake side. In total, the excavated area was 1.29 ar. Particularly noteworthy was the discovery of two large features (4 and 13) of a residential character. The results of previous studies clearly indicate that buildings of this type were located along the edge of the inner area of the stronghold. A large number of finds was recovered during the excavations: 5,082 ceramic fragments, 11,559 animal bone fragments and 121 artefacts.
