Obere Burg ('Upper Castle'), also known colloquially as Burg Neu-Schellenberg, is the larger and older one of the two ruined castles in Schellenberg. Its construction was finished already around 1200. The castles's first appearance in written records occurred on the 10th of January 1348. According to current estimates, it was inhabited until roughly the 16th century, when it was abandoned and ceased to function as a residence. In the following centuries, the castle lost its military purpose and became a ruin. In 1956, Franz Joseph II, Prince of Liechtenstein handed over ownership of the heavily overgrown ruin to the Historical Association of the Principality of Liechtenstein. This institution is the current owner and caretaker of the ruin and oversees its research, upkeep and preservation.
The castle ruin located in the municipality of Schellenberg, Liechtenstein. It lies at the western edge of Hinterschloss, one of the burroughs in the village of Neu-Schellenberg. It is freely open to tourists. Due to its close proximity to Hinterschloss, it is probably the most easily accessible of all Liechtenstein castles. Obere Burg is one of the five existing castles in Liechtenstein and one of the three ruined ones in the country.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.
