During the Nazi occupation it was used for mass executions as part of retaliatory measures against the Czech people after the assassination of Reinhard Heydrich in 1942. About 550 Czech patriots of every social rank lost their lives here, most of them between 30 May and 3 July 1942, when executions took place almost every day. *** "ZASTAV SE NA CHVÍLI, KREV NAŠE VSTOUPILA DO TÉTO ZEMĚ, ALE MY ZNOVU SE VZPŘÍMILI."
