ENThe evaluation, begun in 2006, of building 02 at T. Kosciuškos Street 3 in Vilnius continued in 2009. This building is part of a six building complex which is at the NW foot of the Vilnius hillfort and fortified settlement site. In repairing the building, a trench about 1 m wide and 1–1.3 m deep was dug on the S, E, and N sides. In the eleventh basement room there were plans to lower the floor by up to 20–50 cm, i. e. to the level of the tsarist era floor. Ten test pits about 1 x 1 m in size were excavated. In them were recorded a building’s stone foundations, the mixing of the foundations with late 19th–20th-century layers and undisturbed 18th–19th-century layers. About 12 m2 of the building’s SE annex (room D) was also excavated and a tsarist era sewer discovered in it. In eight rooms (E, F, G, H, I, J, K, and L) the original (tsarist era) surface was discovered. An area of about 520 m2 was cleared. A total of about 630 m2 was investigated.
