There was a small fort in Bettembourg as far back as the 10th century. A tower was added later but was removed when further extensions were made in the 17th century. A second castle was built around 1733 by Lothaire de Zievel and his wife Appolinaire-Agnès-Elisabeth de Haagen Motten. The neighbouring stream known as the Düdelingerbach was probably one of the reasons they chose the site. The rather austere architectural style was typical of the period, especially as the building was designed in the interests of farming.
The oldest part of the castle is the south wing which housed stables and barns. The north wing, now the main part of the U-shaped complex, was added later. In about 1759, Jean-Henri de Zievel charged the architect Rousselet de Boulay with major restoration work. In 1765, on the death of the last member of the De Zievel family, the castle fell into the hands of the castle manager, Marc-Antoine de Verniolles. Various proprietors followed including members of the Hohenzollern-Hechingen-Haigerloch family (1780), Charles Joseph Collart de Donnea, owner of the Dommeldange iron works (1807), followed by various members of the Collart family until 1971. When his wife, Daisy Collart-Weber, died in 1969, August Collart decided to sell the property. The commune of Bettembourg bought the property in 1971 and, after undertaking extensive restoration and reconstruction work, opened the building as the Bettembourg town hall in 1991.
The castle now serves as the commune's administrative building and as the town hall of Bettembourg. One of the important transformations has been the creation of a large cultural room or art gallery. The castle's ornamental wooden panelling and its many fireplaces are of particular interest. The large park surrounding the castle is also open to the public.
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.
