Esch-sur-Sûre Castle was founded around 927 AD, when Meginaud or Maingaud and his wife Hiletrude acquired the site of Esch-sur-Sûre. He built a Romanesque tower eight metres square as well as farm buildings. The castle was considerably enlarged in the Gothic style by the two last Counts of Esch during the 13th century.
With the introduction of gunpowder in the 15th century, additional defences were required. The entire village was reinforced with a solid wall stretching 450 metres around the village complete with two defensive towers. The round watchtower or Lochturm opposite the keep was also built in the 15th century as were the entrance gate and the castle stables. The castle started to deteriorate in the middle of the 16th century and was dismantled in 1685 by the troops of Louis XIV. The outer wall was however left intact as many of the houses used of it for their back walls. The castle fell into the hands of commoners. When Victor Hugo visited the village in 1871, several families were still living there. In 1902, the Egyptian Martin Riano d’Hutzt bought the ruins from the State for 1,000 francs. He charged the architect Charles Arendt with restoration work and the chapel was restored in 1906 but then funds appear to have run out.
Today only the ruins of the castle remain although the State acquired the site in 2005 and began restoration work the following year. The site is open to the public and is illuminated in the evenings.
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.
