This small museum tells some of the shocking story of Paneriai. There are two monuments here: one is Jewish (marked with the Star of David), the other Soviet (an obelisk topped with a Soviet star). From here paths lead to a number of grassed-over pits where, between 1941 and 1944, as many as 100,000 people were murdered.
The Nazis lined up their victims 10 at a time and shot them in the back of the head, allowing the corpses to simply fall into the pits. Several hundred people a day could be killed in this way. The bodies were then covered with sand to await the next layer.
