Sablanceau and Redoute of Rivedoux, Military redoubt in Rivedoux-Plage, France.
The square-shaped fort measures 45 meters on each side and includes two connected artillery platforms along with facilities for the garrison.
Built in 1674 under Vauban's direction, the fortification responded to the 1627 English invasion when 6,000 soldiers landed on Sablanceau beach.
The redoubt represents French military engineering excellence from the 17th century, demonstrating period-specific defensive architecture techniques.
The fortification contains a garrison house, a water well, and an underground storage room designed for extended military operations.
The structure received modifications during Napoleon III's reign in 1862 and later served as a German artillery base in World War II.
