Spøttrup Castle is the best preserved medieval castles in Denmark. The first record of the castle dates from 1404 when it was moved to the possession of Viborg bishop. Bishops built the castle in the 1400s and it was restored in 1525. It consisted of square form castle and two surrounding moats with a drawbridge.
Skipper Clement, leader of the peasant rebellion, attacked to the castle during the so-called Count's Feud (civil war 1534-36). After Reformation the Spøttrup was reduced to the Crown until sold to Henrik Below in 1577. Since the 18th century Spøttrup moved to the hands of several families and it slowly decayed. The restoration started in the early 20th century and in 1941 the castle was opened to the public as a museum.
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.
