These eighty people were huddled into the Trouillas Tower.

Historically it is known as the Tower de la Glaciere; but why change this name of the Trouillas Tower?

It had been the scene of the inquisitorial tortures.

One can still see on the walls the greasy soot which rose from the smoke of the funeral pyre where human bodies were consumed.

Nothing is wanting.
