Fodor's Expert Review Museo del Congreso y de la Inquisición
Editor's Note: This property is currently undergoing renovations.
Visit the torture chambers of the Spanish Inquisition, where life-size exhibits illustrate methods of extracting "confessions" from prisoners accused of crimes against the Catholic Church. You can only visit the museum on hourly tours, and they offer just a few tours in English per day, so you'll want to reserve ahead of time. In contrast to the grisly displays, the 18th-century building is quite lovely, especially the coffered ceilings.
