Crypte Archéologique de Nice

The Crypte Archéologique de Nice opened after tram construction work in the 2000s revealed extensive medieval remains beneath the city centre. The underground museum preserves walls, towers, water channels, and domestic structures from the 10th to the 16th centuries — the layers of settlement that preceded the Baroque city visible at street level today.

The entrance is discreet, reached via a staircase on Place Garibaldi. The site is small but well-interpreted, with lighting and display cases that give excellent context for what the walls mean. It is rarely crowded and provides a genuine sense of the city's layered history, connecting the Roman era above at Cimiez with the medieval period below the current streets.

A story
When Nice built its tram system in the 2000s, excavations beneath Place Garibaldi and the surrounding streets uncovered the intact remains of the medieval city that predated the current Vieux Nice — towers, wells, walls, and streets from before the 17th-century rebuilding campaign. The city chose to preserve and display the finds rather than fill them in, creating a new underground museum directly beneath the tram tracks.
