All Luciano Faggiano wanted when he purchased the seemingly unremarkable building at 56 Via Ascanio Grandi was to open a trattoria. The only problem was the toilet. Sewage kept backing up. So Mr. Faggiano enlisted his two older sons to help him dig a trench and investigate. He predicted the job would take about a week. ...“We found underground corridors and other rooms, so we kept digging,” said Mr. Faggiano, 60. His search for a sewage pipe, which began in 2000, became one family’s tale of obsession and discovery. He found a subterranean world tracing back before the birth of Jesus: a Messapian tomb, a Roman granary, a Franciscan chapel and even etchings from the Knights Templar. His trattoria instead became a museum, where relics still turn up today.

Italy is a slag heap of history, with empires and ancient civilizations built atop one another...
