Beneath the Monumental Complex of Santa Chiara in central Naples lie the remains of a Roman bathing establishment dating to the 1st–4th centuries AD, unearthed during post-war reconstruction work in the 1950s. Now accessible through the complex’s museum, the excavations reveal an extraordinary stratigraphic sequence from Roman thermae to medieval monastic occupation, offering visitors an underground journey through more than fifteen centuries of urban life in what is today one of Italy’s most visited historic city centres.

Overview
The archaeological section of the Santa Chiara Museum presents the stratified remains discovered beneath the Franciscan complex during restoration following the 1943 bombing. The excavations are among the most significant urban archaeological finds in Naples, documenting the continuous occupation of this city block from antiquity through the medieval period. A virtual 360° tour extends access to visitors who cannot physically descend into the site.
History
When Allied bombs destroyed the Baroque interior of Santa Chiara on 4 August 1943, subsequent excavation of the debris revealed extensive Roman structures below the monastic floor level. Archaeologists identified the remains as a substantial thermae complex — public baths — operating from the 1st to at least the 4th century AD. The site was later incorporated into the museum programme of the complex and opened to the public alongside the majolica cloister.
What you see
Visitors descend to view the preserved hypocaust system (underfloor heating) of the Roman baths, sections of mosaic pavement, and the foundations of subsequent medieval building phases. Display cases contain ceramics, amphorae fragments, coins, and small finds recovered from the dig, spanning Roman to Angevin periods. The 360° virtual tour, accessible online, allows remote exploration of the underground chambers with annotated hotspots.
Cultural significance
The excavations provide rare physical evidence of Roman Naples (Neapolis) beneath the medieval street grid, contributing essential data to the urban archaeology of the city. Their inclusion within a functioning Franciscan complex illustrates the layered continuity characteristic of Neapolitan historical topography, and the site forms part of the UNESCO-listed Historic Centre of Naples.
