Ligny Tower is a coastal watchtower built between 1671 and 1672 at a strategic position on the city's western coast. Today, the tower is in good condition, and it is open to the public as an archaeological museum.
Ligny Tower was built on a narrow strip of land on Trapani's western coast, to defend the city from attacks by the Barbary corsairs. It was named after the Viceroy of Sicily, Claude Lamoral, 3rd Prince of Ligne, who had ordered its construction. The tower was designed by the Flemish architect Carlos de Grunenbergh. It has a square base with scarped walls, with four corner turrets which originally contained lanterns.
A passage connecting the tower with the mainland was built in 1806, and guns were installed on the tower's roof until 1862. It was subsequently used as a semaphore station, but it was eventually abandoned.
In World War II, the tower was used by the Regia Marina and was armed with anti-aircraft guns.

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.
