The current Holy Trinity Church in Gävle was inaugurated in 1654. It replaced the medieval church destroyed by fire. It was restored in 1728 and the tower was added in 1779-1781. The church is best known of its altar and pulpit made by Ewerdt Friis (died in 1672). He is buried to the church. There is also a runestone called Söderbystenen in the porch. It was carved in the mid-1000s in honor of Egil, who was killed in a foray to Finland.
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.
