The island of Helgö is probably best known for a major archaeological area. The old trading town on Helgö began to emerge around the year 200 AD, 500 years before the well-known Birka. The first archaeological excavaton in 1954 found not only remains of the early settlement, but also a workshop area that became of international interest.
Among the finds were a small Buddha statuette from North India and a christening scoop from Egypt, both dating from 6th century. The Indian Buddha statuette, the Irish crozier and the Egyptian scoop which were found on Helgö, are presently on display in the Swedish Museum of National Antiquities in Stockholm.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.
