The paper focuses on an extract from the treasury archive of Vilnius Lower Castle from the 1640s. The research provides new data on the sociotopography of a part of the city of Vilnius and the suburb of Antakalnis (Antokol) in 1566 and reveals the fate of some documents kept in the treasury archive after 1655, when the Russian army occupied Vilnius and a fire ravaged the archive. The extract, which is published for the first time in this article, is included in the appendix.
