Origin and history
The Four Plateau Lighthouse, also known as the Crusic Four Lighthouse, is a 23-metre-high maritime building built on a rocky plateau west of the Crusic in the Atlantic Ocean. Its strategic location in southern Brittany makes it an essential bitter for navigation, reinforced by its distinctive spiral motif, similar to that of the Contis lighthouse.
The construction of the lighthouse, led by Chief Engineer Joseph Marie Rapatel and his assistant François Plantier, began in 1816 and finished in 1821, with a commissioning in January 1822. In 1946, its height was increased by six metres. Automatized in 1983, it is now remotely controlled and unguarded. The lighthouse was listed as a historic monument in 2011, and was classified in 2012.
In 2019, La Poste paid tribute to this maritime heritage by integrating into a stamp book entitled "Remarks of our coasts", highlighting its cultural and historical importance. The lighthouse is referenced in the Mérimée base, dedicated to the French architectural heritage.
