LTVilniuje, Trakų g. 12/14 2012 m. liepos-lapkričio mėnesiais tirtas sklypas, kuriame buvo atnaujinti namų restauravimo darbai. Jų metu reikėjo pažeminti vidinio kiemo lygį, pakeisti seną šiluminę trasą, nutiesti naujas nuotekų trasas, po to vykdyti pastatų Trakų g. 12/14 R, V, P ir Š korpusų pamatų sanavimo (pamatų hidroizoliacijos) darbus. Tarp pastatų Trakų g. 12 R ir Trakų g. 14 Š, P bei R korpusų susidarė uždaras kiemas, į kurį galima patekti tik iš Trakų gatvės pusės. Iš viso 2012 m. tyrimų metu surasta 806 vienetai radinių. Pagal buvusių dirbinių naudojimo paskirtį bei medžiagas, iš kurių jie pagaminti, radiniai skirstomi į 5 grupes. Gausiausią radinių grupę sudaro buitinė keramika (iš viso 587 vienetai). Kitų radinių skaičius ženkliai menkesnis. Tarp plokštinių koklių dominuoja plokštės, padengtos žalios spalvos glazūra-tai yra spalva, būdinga XVI a. III ketvirčiui-XVII a. I pusės koklių puošybai. Keletas radinių įgavę raudoną atspalvį. Aptikti kelių skirtingų koklių piešinių motyvai-tęstinio ornamento, puošti kesonu, gvazdikais, augaliniu motyvu. Didesne įvairove nepasižymi metalo radiniai. Jų rasta 10 vienetų. Tarp metalinių radinių gausiausiai rasta kaltinių vinių-6 vienetai. Pastarieji radiniai dominuoja visame Vilniaus senamiesčio kultūriniame sluoksnyje. Kitų radinių rasta po vieną: raktas, pasaga, saga, sagtis. [...] [p. 501-502, 504-505].
ENDuring 4 July-17 October 2012, a field survey was conducted at Trakų 12/14 in Vilnius during the removal of the courtyard’s surface, the waterproofing of the building’s foundation, and the replacement of the old heating line route and a field evaluation during the digging of a sewerage line route and the excavation of a test pit at the site of a future sewer well. Roughly 680 m2 was investigated during the survey and roughly 150 m2 during the evaluation. Sterile soil was reached in the N part of the courtyard at a depth of 3.2–3.5 m. Towards the S, the cultural layer thinned out and at Trakų Street it was reached at a depth of 2.6 m. A row of stones bound with clay and beside them to the W a roughly 6 cm thick layer of slag with an admixture of partially melted stove tiles were discovered at a depth of 1.2 m in the N part of the courtyard (test pit 2) during the survey. It is thought that this is the remains of a 17th century furnace. Beside it was found plain stone paving, which was the surface of the 16th–17th century courtyard. The remains of many 17th–18th century walls were recorded during the investigation. A 60 cm wide, 16th–17th century red brick wall over 7 m long and running towards the N parallel to the W wall at Trakų 12 was discovered in the trench in the S part of the courtyard. The remains of 17th century structures were found in the S part of the courtyard between the buildings at Trakų st. 12 and 14 and the entrance from Trakų street. These are probably the remains of the former Radvila Palace complex, which was demolished during the mid 17th century war. A 94x70 cm stone with engraved symbols and the year of the building’s construction in 1529 was found at a depth of up to 1.06 on Trakų street. A brick with an engraving was found in the foundation wall of another building.The bottom cultural layers of the excavated plot can be dated to the 16th century. 806 finds were discovered in 2012. The most abundant find group consisted of household pottery (a total of 587 sherds), pot fragments predominating (468 sherds, 79.73 %). In addition to them, plate fragments (41), bowls (23), vessel handles (23), cups (10), pitchers (10), frying pans (7), beakers (2), a lid, an oil container, and a pipe were also discovered. Sherds of several imported vessels: fragments of white clay Kielce pottery were also encountered among the finds. The second most abundant find group consisted of structural ceramics, a total of 203 finds (25.19 % of the total number). Green glazed panels characteristic of decoration in the third quarter of the 16th-first quarter of the 17th century dominated among the panel stove tiles (Blattkacheln). Several different stove tile drawing motifs were found: continuous designs and coffer, dianthus, and floral motifs. Ten metal artefacts were found: 6 hand-forged nails, a key, a horseshoe, a button, and a buckle.
