In 1919, after the
October Revolution, the monastery was confiscated. It was closed in 1927 by the Soviet government and subsequently used for various purposes. From 1927 to 1939 there was a
work camp for underage criminals. In the period 1939 to 1941, during the first years of
World War II, the monastery was a
prisoner of war camp of the Russian secret service
NKVD, which held approximately 7,000 Polish
prisoners of war who had been taken captive by the
Soviet Union following the Soviet invasion of Poland in September 1939. Almost all of the prisoners were subsequently executed in April 1940 in Kalinin (now
Tver) and then buried in mass graves in
Mednoye, an act which became known as the
Katyn Massacre. Amongst those killed were Polish officers, lawyers, policemen, teachers, doctors, and other members of the
intelligentsia. From 1941 to 1945 there was a hospital in the building complex, and again from 1945 to 1960, a camp for minors and orphans. From 1960 to 1971 the monastery was used as a
retirement home, and from 1971 to 1990 a
hostel for tourists. ==Current status==
