Bottna Church dates from the 12th century when the sea level was much higher, possibly reaching the foot of the hill on which the church stands. The church retains the character of the Middle Ages when entrances were on the southern long wall. The door was moved, but the doorway remains, where there is a carved stone relief.The walls surrounding the basilica and parts of the chancel are original. Additions were made to the chancel during the 16th or 17th centuries. The altarpiece, possibly a war trophy from Germany during the Thirty Years' War, was a gift from local man Bishop Johan Wingård. The church bell, cast in 1736, hung in a separate belfry until the present tower was built.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.
