1. Oubliette Marker

Inscription. Below your feet is what is called an ‘Oubliette’, a fifteen metre deep pit, with a conical ceiling. Its only entrance was from above.

If your arrival was unwelcome, as you stepped on a certain paving stone, the guard could pull a lever on the wall. The stone would turn over and the ground would seem to swallow you up.

Oubliette comes from the French to forget — and forgotten you would be.
