LT2017 m. tirtame sklype žvalgomuosius tyrimus 2012 m. atliko R. Šmigelskas (ATL 2012 metais, 2013, p. 519–520). Ištyrus 8 šurfus fiksuotas 3,2–5 m storio kultūrinis sluoksnis. Viršutinėse šurfų dalyse tirtos iki 2 m storio XIX-XX a. supiltos griuvenos, tikriausiai atvežtos iš kurios nors Vilniaus miesto vietos. Giliau tirtas 0,4–1,2 m storio juodos durpingos žemės sluoksnis su XVII–XVIII a. radiniais. Giliau tirti uždurpėję sluoksniai. Aptikta dirbinių iš odos fragmentų, XVII–XVIII a. datuojamų medinių konstrukcijų. 2017 m. suplanuota įrengti naujus inžinerinius tinklus Lietuvos mokslų akademijos Vrublevskių bibliotekos pastato Žygimantų g. 1 kieme ir aplinkoje. Suprojektuotų inžinerinių tinklų vietose atlikti žvalgomieji tyrimai, ištirtas 41,8 m² plotas (10 šurfų). Atlikus žvalgomuosius tyrimus nustatytos preliminarios vietos, kur yra išlikę archeologiškai vertingi kultūrinio sluoksnio horizontai. Tokiose vietose 2017 m. birželio–lapkričio mėnesiais atlikti detalieji tyrimai, o likusiose vykdyti žvalgymai. Detaliųjų tyrimų metu ištirtos 9 perkasos ir 6 šurfai (415 m2 ). Iš viso 2017 m. ištirtas 456,8 m2 bendras plotas, žvalgytas 910 m2 plotas. 2017 m. tyrimų metu nustatyta, kad XVI–XVII a. kultūrinio sluoksnio horizontai geriausiai išlikę sklypo centrinėje ir PR dalyse (perkasos 1, 2, 9).

ENDuring a 2017 evaluation in the courtyard of the Wróblewski Library building of the Lithuanian Academy of Sciences at Žygimantų St. 1, Vilnius, and in its vicinity, ten test pits (41.8 m2 ) were excavated. During the excavation, nine trenches and six test pits (415 m2 ) were excavated, a grand total of 456.8 m2 . In addition, 910 m2 were surveyed. The earliest 16th–17th century cultural layer horizons survived the best in the central and SE parts of the plot (trenches 1, 2, 9). In trenches 5 and 6 these horizons were already not as rich. In the rest of the excavated locations the cultural layer horizons from this period survived fairly fragmentally, having been disturbed by the digging, reshaping, and backfilling of ponds in the 18th–19th centuries. The 16th–17th century cultural layer horizons are 10–60 cm thick. The majority of the finds consisted of glazed and unglazed sherds of hand thrown pots. The sherds of 16th–17th-century both hand thrown pots and stove tiles are fairly fragmentary, only several more intact finds having been encountered. A large quantity of 16th–19th-century finds (household pottery, stove tiles, leather artefacts, numismatic material, metal artefacts, and animal bones) were discovered in the fill soil.The late 18th early 19th century structures recorded during the investigation are partially reflected in the 1808 plan of the city of Vilnius; structures (the remains of buildings) were recorded in trenches 1, 6, and 7 and in test pits 7, 8, and 15 and correspond, although with a certain degree of error, to the situation of the plot portrayed in the plan. The former pond contours recorded in trenches 2 and 7 coincide with the NE and SE edges of the large pond portrayed in the 1808 plan. The investigation showed that the situation portrayed in old cartographic material is not precise as the former pond’s edge discovered in trenches 3 and 4 shows that the layout of the plot’s NW part to have been somewhat different. Based on the arrangement of the recorded structures, it is possible to think that during the 17th–19th centuries the plot’s central part, where the ponds and orchards existed, had not been developed. The 17th–19th century buildings stood on the plot’s N and E edges.
