The park was finished in 1745, among other things with a vineyard - the oldest existing in Denmark. Since 1912, the place been owned by Algreen-Ussing family. They run Tirsbæk as a combined arm and forestry as well as rental of homes for private persons and companies. The former stable has been converted to an exclusive restaurant, Restaurant Slotsstalden. The castle is not open to the public, but a Christmas market is held every year, where it is possible to walk around the yard and a few of the former farm buildings.
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.
