By opening up their home to those hunted down by Germany’s Nazi regime, the Ten Booms knowingly put their own lives at risk. But they felt it as their duty to help“God’s chosen people” and those who were on their side. The Ten Boom House, where father Casper ten Boom and his daughters Betsie and Corrie helped to save dozens of lives during Nazi occupation, has been a museum since 1988. When inside this old building, guests can begin to imagine what it must have been like to hide and live here.
