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.
I wonder if they were emptied at some point or they just let birds eat their remains and peck them to pieces that could fall through the bottom...
The corpses were there for 50 years so a little of both but more of the first.
