Speaking of the Inquisition, this is the Inquisitor’s Palace — one of the few remaining in Europe, and the only one that is open to the public. (Most were destroyed during the French Revolution, as the church was seen as the bulwark of the abusive nobles.) This palace was the seat of the Maltese Inquisition from 1574 to 1798, and as such it was the site where heretics (Jews, Muslims, Protestants, and witches) were tried and punished.
