Tomarps Kungsgård Castle was probably erected as a Renaissance building in the mid-16th century. It was composed of four, two story high wings with brick roof surrounded by a narrow square yard. The middle part of the northwing consists of the remains of a building from the Middle Ages. I the south-east corner of the yard there were a tower until the late 18th century. The castle belonged to the Brosterups linage in the late 15th century and were then transferred to the Gjedde family. When Borgholm was handed over from Sweden to Denmark after Treaty of Copenhagen in 1660 the Castle was, together with 17 other acreages, handed over to the Swedish king as compensation. It was then used for housing the lieutenant colonel and later the colonel. Today it is used for vernissage.
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.
