Lidice is a town in the modernday Czech Republic.
In 1942 the village of Lidice was erased by the Nazis. The adult men were shot and piled into a mass grave, the women and children shipped off to concentration camps, the town itself razed to the ground and salted over (according to the Czech professor of my Eastern European Communism course) to prevent anything from growing there. This was a reprisal for Operation Anthropoid, the only successful resistance assassination of a major Nazi leader.
The village was rebuilt in 1949 near the original site. There’s a monument with statues of 82 children.
