Algajola is an ancient Genoese fortress dating back to the 16th century. The Ottomans, who sacked Algajola in 1643, obliged the Genoese to destroy the fortress. Genoa built a new castle in 1664. Today, the Algajola Castle is one of the main tourist attractions of this town.
The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
