If you crane your neck and look up while standing in front of St Lambert's Church in Münster, Germany, you can make out three iron cages hanging from the church's steeple, just above the clock face.
The cages are empty, but five hundred years ago they held the mutilated, rotten corpses of three revolutionaries who led one of the most brutal Protestant revolutions in history.
Pretty sure this is what Jesus was calling for in the bible. Well done.
