Schloss Heiligenberg is a Renaissance-style castle owned by the Fürstenberg family. It is located on a plateau 730 metres above sea level, with views down onto the Bodensee and the Alps. It was first built in the Middle Ages - in 1250 count Berthold of Heiligenberg built a burgh on the site, which was bought in 1277 by count Hugo of Werdenberg. Under the counts of Werdenberg-Heiligenberg, the castle expanded during the late Middle Ages.
Through countess Anna of Werdenberg's marriage to count Friedrich zu Fürstenberg in 1516, the burgh passed to the house of Fürstenberg in 1535 - it is still owned by that family today. Shortly before his death in 1559, Friedrich decided to remodel the castle in the Renaissance style. The building as it is seen today dates to count Joachim (1538–1598), who from 1560 to 1575 rebuilt the late medieval burgh into a 'schloss', with a Renaissance-style courtyard and an extended ballroom wing to the south.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.
