With warming sparks and flames, the Archaeological Open Air Museum Oerlinghausen will welcome you on this day. Söhnke Raimann uses many examples to show how lighting a fire worked in the days without matches and lighters and tells interesting stories about it. Experience how a spark turns into a cozy fire. Learn and feel how important fire was and still is for us humans. Söhnke Raimann's extensive repertoire does not neglect fans of red Indians who want to know how their role models made fire at the time. The sparks can be seen particularly beautifully in the darkness of our hall building. So come and visit us if you want to experience an unforgettable day!
