La Rochelle, the prefecture of Charente-Maritime, has made the most of its many attractions to charm visitors.

Its three towers, listed as Historic Monuments since 1879, are remains of the medieval fortifications.

At the very top, you can enjoy a lovely view of the city and the harbour!

The other two towers, built at the end of the 14th century, were used to defend the port for five centuries. The tallest, the St. Nicholas Tower, is 42 metres tall and offers an impressive view from its wall walk. The Chain Tower, which closed the channel to boats, is connected to the Lantern Tower by a curtain wall. The Great Clock Gate (Porte de la Grosse Horloge), topped by a belfry, was added in the 15th century to the city wall.

On the banks of the Charente, Rochefort has kept many reminders of its glorious maritime past. This prestigious city, created by Colbert on the initiative of Louis XIV, owes its fame primarily to its military Arsenal, which produced 550 ships over two-and-a-half centuries.

It is here that the Hermione, the legendary frigate that carried the Marquis de La Fayette, was built. Its amazing replica, built thanks to a community project using the materials and techniques of the time, was completed in 2015 after 18 years of work. Today, it's a fascinating attraction for children and adults to visit.

Housed in a superb 17th-century building measuring 374 metres in length, the Royal Rope Works is an important part of Rochefort's maritime history. This factory, which manufactured ropes for the French Royal Navy, now houses the International Sea Centre.

The National Navy Museum is located in the Hôtel de Cheusses mansion, one of the oldest buildings in the city. It has a hundred or so scale models and collections about the Arsenal's history to discover. The former School of Naval Medicine, founded in 1722, was the first in the world to train surgeons to serve on warships.

The unusual house where Pierre Loti was born is now a museum exhibiting objects and exotic memorabilia that belonged to the famous writer and naval officer from Rochefort. The Museum of Old-time Businesses, with reconstructions of workshops and shops from 1900 to 1945, is also worth a visit, as is the Museum of Art and History, housed in the Hôtel Hèbre, a beautiful 18th-century mansion.

Brouage, labelled one of the Most Beautiful Villages in France, is a former stronghold in the middle of the marshes. It's well worth discovering for its ring of ramparts as well as its watchtowers, bastions and posterns which bear witness to its medieval past. The Château de La Gataudière, an 18th-century stately home and listed Historic Monument, was once owned by an engineer to the King, François Fresneau, who was also the inventor of rubber.
