"This crypt filled with the mummified remains and skeletons of friars of the Capuchin order is one of Rome's quirkier, more sombering sites. Located just off the glitzy Via Veneto underneath the Church of Santa Maria della Concezione, it contains a series of chambers adorned by the skulls and bones of 4,000 friars arranged in intricate patterns and chandeliers. Though open to children, it's strongly advised to think twice before bringing in anyone who is easily spooked." - Laura Itzkowitz
