A note published in the journal "Sztuki Piękne",1931, no. 10, p. 392 (public domain, reprinted from the Library of the University of Silesia, Katowice) contains a description by arch. Juliusz Kłos's description of the work carried out and its results in the Chapel of St Casimir in Vilnius, which, among other things, ruled out that the chapel was the burial place of Alexander Jagiellon and Barbara Radziwiłłówna. Eventually, later that year, researchers managed to find the tombs in the Cathedral.
