Château de Castries has belonged to the House of Castries since 1465. In 1565, Jacques de Castries undertook the building of a new château. The garden was laid out by André Le Nôtre in 1666. The aqueduct, to water the garden, was built by Pierre-Paul Riquet.
The main house was looted and damaged during the French Revolution of 1789 and was restored in 1828. In 1935, it was bought back by René de La Croix de Castries. In 1985, he donated the house to the Académie française. It is open to the public.References:
Goryōkaku (五稜郭) (literally, 'five-point fort') is a star fort in the Japanese city of Hakodate on the island of Hokkaido. The fortress was completed in 1866. It was the main fortress of the short-lived Republic of Ezo.
Goryōkaku was designed in 1855 by Takeda Ayasaburō and Jules Brunet. Their plans was based on the work of the French architect Vauban. The fortress was completed in 1866, two years before the collapse of the Tokugawa Shogunate. It is shaped like a five-pointed star. This allowed for greater numbers of gun emplacements on its walls than a traditional Japanese fortress, and reduced the number of blind spots where a cannon could not fire.
The fort was built by the Tokugawa shogunate to protect the Tsugaru Strait against a possible invasion by the Meiji government.
Goryōkaku is famous as the site of the last battle of the Boshin War.
