Stolin Prison
On September 11, 1942 (or September 10, according to some other sources), the eve of the Jewish holiday of Rosh Hashanah, the twelve members of the Judenrat were ordered to come to the headquarters of the security police. They were then taken into the prison courtyard and shot.

Stasino Ravine
The population of the Stolin Ghetto was liquidated on September 11, 1942. First, the ghetto inmates were forced to assemble in the town marketplace. According to some testimonies, they were ordered to leave their outer garments behind, and were then taken on trucks to the designated pits, which had been dug back in the Soviet period, during the construction of an airfield. The pits lay 3 kilometers northwest of the town, in the vicinity of the Stasino Ravine near the former Radziwiłł mansion. The victims were led in groups to the edge of the pits and forced to lie down in them. As soon as one batch was shot, the next one would be brought over, and the people would be forced to lie down atop the bodies of their murdered fellows. The total number of victims of that massacre is estimated at around 8,000.
