LT2022 m. rudenį pratęsti po ilgesnės pertraukos 2020 m. atnaujinti (ATL 2020 metais, 2021, p. 283-292) archeologiniai tyrimai Vilniaus Jonušo Radvilos rūmų pastatų komplekso (UK752) teritorijoje Vilniuje, Vilniaus g. 24. Ruošiamasi rekonstruoti J. Radvilos rūmus, išryškinant neišlikusias rūmų dalis, moderniomis priemonėmis atkartojant buvusį rūmų pavidalą. Projektuotojams norint įgyvendintišį siekį buvo svarbu žinoti tikrąsias rūmų neišlikusių paviljonų vietas, todėl vienas pagrindinių 2022 m. vykusių žvalgomųjų tyrimų tikslų buvo identifikuoti J. Radvilos rūmų neišlikusių paviljonų liekanų kampų tikslias vietas, nustatyti tų liekanų parametrus. Taip pat siekta nustatyti, ar konkrečioje kiemo dalyje, plote, kuriame 1990 m. buvo atlikti detalieji tyrimai, yra galimybė įrengti paviršinio vandens surinkimo įrenginius - infiltracines talpas [p. 186-187].
ENIn autumn 2022, archaeological excavation continued in the territory of the Janusz Radvila Palace in Vilnius, located at 24 Vilniaus St. The palace, built in the mid-17th century and badly damaged during the Moscow War, is located in the W part of the Old Town, beyond the city’s defensive wall. The objectives of the exploratory excavation carried out in 2022 were to identify the exact locations of the corners of the remains of the pavilions of the Radvila Palace and to determine the parameters of those remains. To that end, archaeologists had already excavated test pits as early as the end of the 20th century. Seven test pits of different sizes were investigated, covering a total area of 94.75 m2. The excavation managed to precisely locate the remains of the central pavilion of J. Radvila, the shape of which was nearly square, approximately 18 x 18 m in size. No remains of the SW pavilion or of the connecting second E wing were found. Test pit 7 was found to contain 18th-century masonry structures, built in at least two phases. The extension of this test pit allowed the excavation of deposits disturbed during previous excavations, the investigation of a small segment of an archaeological layer dating to the 15th-18th centuries, and the investigation of features cut into the sterile soil and dating to the 15th-17th centuries. These features were left unexcavated in previous years. The archaeological layer in test pits 2, 5 and 7, in the freshly exposed areas free of features, was 1.7-2.2 m thick, with the earliest level dating back to the 15th century based on the data of previous studies.
