Fodor's Expert Review Cimitero delle Fontanelle

Once a quarry for the city's tufa stone, this site was first used as a mass burial ground in the 16th century following a devastating plague. Skulls and bones of the city's unfortunate citizens (including, some say, those of the poet Leopardi) are piled high against the walls in this fascinating and macabre site. It was closed in March 2020 due to water infiltration and at the time of writing no reopening date had been confirmed, so check before making the long trek to this fascinating site.
