An oubliette is a dungeon reached only through a hole above. Thrown into the oubliette, the castle oubliette, forgotten in an oubliette.
The name says the purpose: it is from the French for to forget, and a prisoner put into one was not meant to come out. Genuine examples are rarer than castle tours suggest, since many such pits were storerooms.
