Kuitia is the oldest remaining manor house in Finland. It was built of stone probably in 1480s by noble Joachim Fleming. There has been a manor house in same location from the beginning of the 15th century. Earliest known owner of Kuitia was Maunu Tawast, a bishop of Turku, who donated manor to his brother in 1439.
Because Danish soldiers plundered coastal villages in the 15th century, Kuitia was built also for defensive purposes. Originally the present stone house was part of a foursquare, inner court structure. Current wooden residence was built in 18th and 19th centuries. Kuitia has been privately owned by af Heurlin family about 150 years and is still in living use. Kuitia is open for visitors only with group excursions.
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.
