Today, St. Gereon is not only a church but also a memorial. In the former baptistery, one side of which is entirely made of stained-glass windows, a permanent exhibition will soon be dedicated to the former parish priest, Franz Boehm. He preached at St. Gereon from 1938 to 1944 as a resistance fighter against National Socialism and died a martyr in the Dachau concentration camp in 1945.
The exhibition will be open to visitors every day – except during church service times.
Outside the church is the Franz Böhm Monument, a work of art created by Thomas Kesseler and an impressive memorial that invites visitors to pause and reflect on Monheim's courageous pastor during the dark years of Nazi rule.
