Fodor's Expert Review Ss. Giovanni e Reparata

The unusual element at this church is an archaeological site where five layers of Luccan history were revealed when it was discovered in 1969. Paths and catwalks suspended above the delicate sites in the grottoes under the church enable you to wander from one era to another—from the 2nd-century-BC site of a Roman temple through the 5th, 8th, 9th, and 11th centuries. After leaving the underground sights, the 12th-century church feels almost modern.
