La Citadelle de Blaye.

On the right bank of the Gironde Estuary 56km north of Bordeaux lies the old Citadelle de Blaye which historically guarded the main entry point to Bordeaux.

In ancient times Blaye (Blavia) was a port of the Santones. Tradition states that the Frankish hero Roland was buried in its basilica, which was on the site of the citadel. It was early an important stronghold which played an important part in the wars against the English (who burnt it in 1352) and the French Wars of Religion (when it was the site of a Spanish naval victory in 1593). The duchess of Berry was imprisoned in its fortress in 1832-1833.

The town was formerly named Blaye-et-Sainte-Luce and was renamed Blaye in June 1961.

The town has a citadel built by Vauban on a rock beside the river, and embracing in its ancient ruins of an old Gothic château. The latter contains the tomb of Charibert II, king of Aquitaine, and son of Clotaire II. Blaye is also defended by the Fort Paté on an island in the river and the Fort Médoc on its left bank, both of the 17th century.

The citadel of Blaye, its city walls, the Fort Paté and the Fort Médoc (the latter in nearby Cussac-Fort-Médoc) were listed in 2008 as UNESCO World Heritage Sites, as part of the "Fortifications of Vauban" group.

Himeji Castle

Himeji Castle is a hilltop Japanese castle complex located in Himeji in Hyōgo Prefecture. The castle is regarded as the finest surviving example of prototypical Japanese castle architecture, comprising a network of 83 buildings with advanced defensive systems from thefeudal period. The castle is frequently known as Hakuro-jō ("White Egret Castle") or Shirasagi-jō ("White Heron Castle") because of its brilliant white exterior and supposed resemblance to a bird taking flight.

Himeji Castle dates to 1333, when Akamatsu Norimura built a fort on top of Himeyama hill. The fort was dismantled and rebuilt as Himeyama Castle in 1346, and then remodeled into Himeji Castle two centuries later. Himeji Castle was then significantly remodeled in 1581 by Toyotomi Hideyoshi, who added a three-story castle keep. In 1600, Tokugawa Ieyasu awarded the castle to Ikeda Terumasa for his help in the Battle of Sekigahara, and Ikeda completely rebuilt the castle from 1601 to 1609, expanding it into a large castle complex. Several buildings were later added to the castle complex by Honda Tadamasa from 1617 to 1618. For over 400 years, Himeji Castle has remained intact, even throughout the extensive bombing of Himeji in World War II, and natural disasters such as the 1995 Great Hanshin earthquake.

Himeji Castle is the largest and most visited castle in Japan, and it was registered in 1993 as one of the first UNESCO World Heritage Sites in the country. The area within the middle moat of the castle complex is a designated Special Historic Site and five structures of the castle are also designated National Treasures. Along with Matsumoto Castle and Kumamoto Castle, Himeji Castle is considered one of Japan's three premier castles. In order to preserve the castle buildings, it is currently undergoing restoration work that is expected to continue for several years.
