"A sombre, thought-provoking crypt beneath the church on Via Vittorio Veneto that displays the carefully arranged bones of over 3,700 Capuchin friars, assembled into intricate patterns and macabre artworks that invite reflection on life and death. Visits must be planned in advance—photography requires a permit, English guided tours cost around €80 and should be booked at least two weeks ahead, and visitors are required to wear clothing that covers the knees (minors may enter when accompanied by adults)." - SilverKris
