The church ruin at Rokoberget is the remains of a church dedicated to the archangel St. Michael. The church was built of stone and was sited at the top of the Rokoberget hill. St. Michael's church was first mentioned in a papal letter of 1254 and has been a wayside church, but historians disagree about whether the passers-by were pilgrims or Swedes on their way to the market at Hamar. The ruins, which are accessible to the public, are fenced in. A path down to the right behind the bell tower leads to a look-out point.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.
