Driving into the village of Treblinka, modern Poland seems very far away. Horse-drawn carts still rumble over cracked pavement on narrow farm roads. This isolation is why the Nazis placed an extermination camp here over seven decades ago. During WWII, 800,000 people – almost all Jewish – were killed at the Treblinka death camp, 2km south of the town. A visit to the site and memorial today is a powerful part of understanding the Holocaust.
