Probably dating from the Middle Bronze Age (1600-1300 BC), Li Mizzani Giants' Tomb is among the few in the island that has retained the stele in its original upright position, 2.8 meters high.The Tomb of Giants Li Mizzani has an external width of 2.45 m. About 300 meters from the grave, to the left of a country house, is less than the perimeter wall and the entrance of the dolmen Luchia; near you you can also see the remains of a nuragic village.
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.
