A graceful neoclassical structure facing the Plaza Bolívar houses this diminutive museum where the Spanish Inquisition once plied its trade. In the 1800s, the building was expanded and rebuilt into the Peruvian senate. Today, guests can tour the basement, where morbidly hilarious wax figures are stretched on racks and flogged – to the delight of visiting eight-year-olds. The old 1st-floor library retains a remarkable baroque wooden ceiling. After an obilgatory half-hour tour (in Spanish or English) guests can wander.
