The grey-stone church of Ärentuna was built around the year 1300. It was probably inaugurated in 1302, when archbishop Nils Allesson visited in Ärentuna parish. The original barrel vault of wood was replaced by brick-made cross-vaults before the church's reopening in 1435. The well-preserved mural paintings, made by unknown “Ärentuna master” date also from 1440-1450s. The bell-tower was reconstructed in 1772.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.
