Fodor's Expert Review La Crypte Archéologique de Nice
Via steel walkways, explore (by tour only) this half-acre archaeological crypt beneath Place Garibaldi, holding the remains of a 14th-century tower and aqueduct that were hidden underground for centuries. When Nice's tram system was being built at the beginning of this century, excavators discovered medieval structures that had been razed by Louis XIV in 1706 and promptly forgotten. The Centre du Patrimoine (Heritage Center) offers one-hour guided tours for up to 15 people, but you must reserve with them directly at 75 quai Etats-Unis. The meeting point—Place Jacques Toja—is just off Place Garibaldi. Bring "sensible shoes," as heels can't be worn in the crypt.
