After the second world war, a considerable part of eastern territories remained outside the frontiers of Poland. This fact signified a further devastation of property, initiated by wartime hostilities, as well as a severance of contacts with the cultural heritage of the once multinational state. The same fate was shared by Jazłowiec, where the former palace, built on the site of the Lower Castle (Castle Hill), was granted to the Sisters of the Immaculate Conception of the Holy Virgin Mary (1863). Under the supervision of Mother Marcelina Darowska, the nuns opened a celebrated and acclaimed girls’ school, active up to the outbreak ofWorldWar II. The tomb used as the burial site for nuns was constructed in the form of catacombs on the western edge of Castle Hill. The article contains an historical outline and an architectonic description of the tombs as well as a proposal for the anti–dampness protection of its structure.
