Roman churches usually aren’t shy about their macabre histories. At Santa Maria dell’Orazione e Morte a nun will be happy to let you photograph their crypt of abandoned bodies in exchange for a small donation. At Santa Prassede a sacristan will give you a pamphlet and helpfully point out the well where St. Praxedis and St. Pudentiana poured the blood that seeped out of the three thousand bodies of martyrs they were hiding. At the famous Capuchin crypt you can even buy postcards of the mummified monks to send to dear friends or enemies.
