The Nazis tore down their notorious Treblinka death camp in 1943 and did their best to hide any physical evidence it ever existed. The strategy mostly worked, but some high-tech archeology is finally revealing the camp’s secrets, reports LiveScience.
British archeologist Caroline Sturdy Colls led a team that conducted the first digs at the site in Poland—Treblinka was actually two separate camps—discovering three previously unidentified mass graves and the apparent location of one of the camp’s two gas chambers.
They found the latter by scanning the ground with lasers to reveal a brick wall and foundation, and Colls says the gas chambers were the camp’s only brick buildings.
