ENIn 2008 the investigation (a total area of 1300 m2) of the Vilnius defensive wall bastion at Subačiaus St. 18 / Bokšto St. 20 was continued. A strip about 100 m long and up to 10 m wide was excavated above the bastion’s gun emplacements (hereinafter called the horseshoe), a strip about 91 m long and 1.8–2.3 m wide along the horseshoe’s interior wall, a 29 m long, 1.8–2 m wide strip along the wall on the S side of the underground part of the tunnel, and triangular areas at the places where the horseshoe and corridors meet. Two cultural layer horizons were distinguished in the gorge. The first (upper) 1–2 m (in places even up to 5 m) thick horizon dates to the second half of the 20th century and is connected with the restoration and repair of the bastion. The second (lower) horizon, which is from 2–3 m to 8.5 m thick, dates to the late 16th – early 17th century and is connected to the bastion’s construction. Two horizon parts are distinguished in it. The sandy layers with isolated finds (pottery, roof tiles, brick fragments, animal bones, and even human bones) are connected with the filling in of part of the horseshoe and the corridor. The brown clay layers without any finds are connected with the waterproofing and reinforcement of the bastion’s underground elements.
