ENIn 2019, there was a wide-ranging announcement in the Lithuanian media: in the Old Town of Vilnius, in the territory between Žygimantų, Radvilų, and Tilto streets, archaeologists found the remains of the legendary Biržai-Dubingiai Radvilos family palace near the Neris river. The existence of the residence of the most powerful family of nobles of the Grand Duchy of Lithuania was known here for a long time from historical sources (the family had nine properties in Vilnius). The property in question, with the palace, is marked in the old plans of the city, and in a drawing from the end of the 18th century, the image of the already decaying but still majestic palaces is commemorated. In 2010, art historian Dr. Birutė Rūta Vitkauskienė revealed the significance of the Radvilos holdings in the vicinity of Lower Castle. At the beginning of the 16th century, this area, known as Puškarnia, was outside the city limits but very closely linked to the castle and the activities of the ruler. There was a cannon foundry, which was reconstructed in 1547 by the Grand Duke of Lithuania Žygimantas Augustas, and people deserving of the rulers favour lived there - nobles, blacksmiths, smelters, and other craftsmen making objects of war. Since 2019, Ignas Sadauskas has been leading archaeological research at the site of the former Radvilos residence, and he shares the latest discoveries, including the discovery of the old part of the palace where Barbora Radvilaitė the future Grand Duchess of Lithuania (1548) and Queen of Poland (1550) could have visited.
