On the same quiet square as St-Pierre, shaded by an old olive tree, this intimate museum offers a quirky diversion. Its few rooms contain a concise and fascinating collection of ancient amphorae gleaned from the shoals offshore, where centuries' worth of shipwrecks have accumulated; by studying this chronological progression of jars and the accompanying sketches, you can visualize the coast as it was in its heyday as a Greek and Roman shipping center. The science of exploring these shipwrecks was relatively new when French divers began probing the depths; the underwater Leicas from the 1930s and the early scuba gear from the '50s on display are as fascinating as the spoils they helped to unearth. Upstairs, a few objects—jewelry, spearheads, pottery shards, and skulls—illustrate the Neolithic and Paleolithic eras and remind you of the dense population of Celto-Ligurians who claimed this region long before the Greeks and Phoenicians. A few of their dolmens and menhirs are still visible on the Estérel. You can use QR codes throughout the museum as a guide; iPads and iPods can be borrowed from reception.
