Though the Urspelt Castle has a history going back at least three centuries, today's building dates from 1860. The origins of the castle go back more than 300 years when it was a small country property. Then in 1860, Amand Bouvier considerably expanded it. A new garden was laid out, now one of the area's most notable parks with its avenues and elm trees. When Bouvier died in 1900, he left a magnificent estate to his nephew Alfred Bouvier but he and his descendents failed to show much interest in the property. During the Second World War, the Germans used the castle as their headquarters for northern Luxembourg until they were forced to abandon it to the Americans during the Battle of the Bulge in the winter of 1944. After the war, the castle fell into disrepair and was used only as a hunting lodge. Towards the end of the 20th century, the deserted building was increasingly invaded by the surrounding undergrowth.
After comprehensive restoration work and additions in 2005, it recently opened as a hotel and meeting centre. An old well, apparently dating back to an 11th-century stronghold, was found and renovated in a restoration. A second tower was added at the far end of the castle to house a lift.
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.
