LTMisionierių vienuolyno statinių ansamblio (UK 761) ir Vaikelio Jėzaus vaikų prieglaudos pastato (UK 33915) teritorijose, sklype Subačiaus g. 26, Vilniuje, kuriame planuojama statyti 4610m2 dydžio pastatą, UAB "Misionierių sodai" užsakymu KVP atliko žvalgomuosius ir detaliuosius tyrimus. Būsimo pastato Š ir P vietose 2015 m. gegužės–gruodžio mėnesiais ištirtas 3325m2 dydžio plotas, PV dalyje (projektuojamos elektros transformatorinės vietoje) iki saugaus 2,6 m gylio ištirti du 2x1 m dydžio šurfai. Tyrimai dėl laiko stokos nebuvo baigti, juos planuojama pratęsti 2016 m. Taigi, tyrinėtoje teritorijoje XVI–XVII a. gyveno ir dirbo amatininkai (metalurgai, keramikai ir galbūt kauladirbiai), kurių dirbtuvės išsidėsčiusios palei šioje vietoje ėjusią gatvę, kuri, spėjama, buvo Rasų gatvės tąsa. Tik nuo XVII a. pabaigos, buvusiuose Jeronimo Sanguškos rūmuose įsikūrus vienuoliams misionieriams, amatininkų dirbtuvės ir gatvės dalis, patekusi į vienuolynui priklausiusį naujai suformuotą sklypą, panaikinti ir įkurti sodai, kurie čia buvo iki XX a. Sklypo PV dalyje atlikus žvalgomuosius tyrimus ir iki saugaus gylio ištyrus du 2x1m dydžio šurfus, nustatyta, jog XVIII a. žemės paviršius šioje vietoje buvo ties Habs 129,10 m altitude. XVII a. čia supilti iki 1m storio žvyro sluoksniai, kurių apačia fiksuota Habs 127,70-128,10 m aukštyje. Žemiau jų slūgso suplautinės kilmės sluoksniai be radinių, kurie tirti iki Habs 126,95 m altitudės. Taigi, tyrinėto sklypo PV dalyje tyrimų metu fiksuota visiškai kitokia situacija.

ENIn 2015, an excavation (a total of 3325 m2) was conducted on the plot at Subačiaus st. 26. Two 2x1 m test pits, in which natural soil was not reached owing to its great depth and the loose nature of the soil, were excavated in the SW part of the plot. It was determined that a cultural layer with abundant finds and a varied thickness had formed during various periods on the plot. At a depth of about 60 cm in the SW part of the plot was an 18th century cobble paving, which had survived fragmentally and which lay atop a layer, up to 50 cm thick, with 17th-18th century finds. Below that, to a depth of 1.7 m, were 17th century gravel fill layers under which lay, to a depth of 2.6m, alluvial layers without finds. The valuable cultural layers around the former hospital building (erected in the second half of the 20th century) had been destroyed during the construction work: in a roughly 10 m wide strip along the N wall and in a roughly 15m wide strip along the S wall. The total thickness of the cultural layer in the N part of the plot was about 2.7 m. The upper, 0.5–2 m thick layers have no archaeological value and formed during the 19th-20th centuries. Under them lies a late 16th-17th century cultural layer, up to 1m thick, with pits from that time and the remains of a late 16th century wooden structure. The remains of a cobblestone carriageway, which dates to the second half of the 17th century and, it is conjectured, could have been part of Rasų street, were unearthed at this location.The original surface, a layer of dark grey sandy soil with small pieces of charcoal and 15th century finds, had survived in the NE and S parts. The 16th-20th century cultural layer in the S part of the plot had a total thickness of 1.9–2.2m. A valuable 16th-17th century cultural layer horizon was recorded from a depth of 1.2 m. In the investigated area, wooden buildings had been erected already in the late 16th century but starting in the mid 17th century both masonry (the remains of three having been unearthed) and wooden buildings (the remains of one with a basement with a stone floor having been found) were erected. Masonry buildings were also built in this area in the 19th century. In the 16th mid 17th centuries, this area was the site of metallurgical, pottery, and perhaps bone workshops: in the S part (area 2) crucible fragments and copper droplets were found, in the N part (area 1) a late 16th century household pottery and stove tile kiln labelled C, two mid 17th century structural ceramics and perhaps household pottery kilns labelled A-B, contemporaneous clay preparation pits 13-14, and a well were discovered. Bone production waste was likewise found in the 17th century layers in the N part of the plot.
