open daily 9AM-12 noon and 3PM-6PM, entrance is €3 - the catacombs of the Capuchin convent located on the Piazza Cappuccini, just west of the city centre, contain over 8000 mummified ex-residents from Palermo and its surrounding villages, some merely clothed skeletons, other remarkably well-preserved and lifelike. Well worth a visit, interesting, if slightly morbid. Children may either find it exciting or terrifying, and it must be the responsibility of their parents to think carefully before taking them. You can arrive via the new tram line that opened in 2015 and a 10- to 15-minute walk. Your visit will not take longer than one hour.
