Known for its white limestone cliffs, La Rochelle enchants. Wander along its bustling harbor, Quai Duperré, savoring the iconic view of the Tour Saint-Nicolas and Tour de la Chaîne, painted by countless artists including Corot, Signac and Vernet. Then take a seat under the awnings of one of the many oceanfront restaurants and have a delicious seafood lunch while watching the sailboats. Look up to see the three medieval towers that once protected the port and are now symbols of the waterfront. The imposing Four Sergeants Tower was formerly a prison, and you can see where the corsairs scrawled graffiti on the walls. Be sure to visit the city aquarium, which holds thousands of species living in re-creations of their natural habitats. You will also appreciate La Rochelle's pedestrian-friendly streets, especially in the city center, which is graced by 17th and 18th century architecture.
