LT2022 m. atlikti nedidelių apimčių tyrimai Vilniaus senojo miesto ir priemiesčių archeologinės vietovės (UK 25504) teritorijoje, esančiose M. Daukšos, Didžiojoje ir T. Kosciuškos gatvėse [p. 388].
ENIn 2022, small-scale excavations were carried out on M. Daukšos, Didžioji and T. Kosciuškos Streets in Vilnius. Two test pits (total area of 3.5 m2) were excavated inside the outbuilding at ЗА M. Daukšos St., which was built in the late 18th or early 19th century, and an area of 48.3 m2 was surveyed in the surrounding area. The test pits revealed an archaeological layer dating from the 16th to the first half of the 17th century, measuring 15-95 cm thick. This layer was recorded at a depth of 80-95 cm from the present-day surface in test pit 1 and at a depth of 0.9-1.2 m in test pit 2. In both test pits, a 19th- and 20th-century fill was recorded above the 16th-17th-century level. In the surveyed utility trenches, mixed fill layers were recorded extending as far down as the sterile soil or at least to the maximum excavated depth, with the exception of two short sections which contained a disturbed 16th- and 17th-century layer or its uppermost level. Two test pits (12 m2) were excavated on the grounds of the so-called Abramavičiai Palace, located at 36 Didžioji St. Three structures were recorded in test pit 1: the foundation of a wall or a fence from the second half of the 17th to the 18th century; the foundation of an unknown structure from the 16th to the first half of the 17th century; and a pavement from the 16th to the first half of the 17th century. In test pit 1, an archaeological layer dating to the 16th-18th centuries was recorded at a depth of 90-95 cm, measuring 0.8-1 m thick. In the S part of test pit 2, the top of the layer dating to the 16th-17th centuries was recorded at a depth of 2-2.1 m, and it included a small number of finds. Sterile soil was recorded at a depth of 2.3-2.6 m. In the N part of test pit 2, a 17th-century layer was reached at a depth of 1.2-1.6 m. The horizon of an undisturbed 16th- and 17th-century layer was recorded at a depth of 2.2-2.65 m.This part of the test pit also revealed two unidentified, heavily disturbed structures, possibly dating to the 16th-17th centuries and to the second half of the 17th-18th centuries. At 34 T. Kosciuškos St., 2 test pits with a total area of 10 m2 were excavated. The site was the presumed location of the Brzostowski Palace, also known as “China”, in the 17th and 18th centuries. The test pits recorded a layer of mixed fill extending to a depth of 0.91.2 m from the surface, which was dated to the 19th-20th centuries. In test pit 1, a 90 cm layer dating to the 16th-18th centuries was recorded at a depth of 1-1.2 m, along with a few scattered finds. Structures associated with a building, potentially dating from the second half of the 17th to the 18th century, were uncovered at a depth of 1.15-1.2 m: a pink clay brick floor dating from the second half of the 17th to the 18th century; and a 17th-century packed clay floor. In test pit 2, a layer measuring 20-30 cm in thickness and dating to the 16th-17th centuries was recorded at a depth of 1.1-1.2 m. Sterile soil was encountered in the test pits at a depth of 1.4-2 m from the present-day surface.
