Between 1944 and 1947 over 700 Lithuanians, Poles and Jews were executed on this site by the forerunner to the KGB and buried in what was at the time State-owned property in the grounds of the 19th-century Tuskulėnų Dvaras manor house. In 1994 the remains of the bodies were discovered and the area has since been turned into a memorial park. The park complex comprises the manor house, the former stable building next door that now houses an art gallery and a smaller house now complete with an interesting exhibition. The jewel in the crown however is the columbarium (kolumbariumas), an extraordinary underground burial chamber that’s more of a mass a mausoleum and where the remains of the deceased are now kept. Tours in English are available, and calling in advance to make sure everything’s open is recommended.
