Saalkirche, today a Protestant church, was constructed on a cross‐shaped floor in the 10th century as a further sacral building in the Ingelheim Pfalz. Thus the imperial palace reached its closed U‐shaped form, which had already been foreseen in the Carolingian building concept. In the following centuries the church was constantly remodelled, mainly in the 12th century. Integrated into a monastery in 1345, the church overcame the resettlement of the former Pfalz area, the so‐called ‘Ingelheimer Saal’ to which the name of the church refers. Given up in course of Reformation the building became dilapidated. In 1965 its reconstruction was completed. A small exhibition on the Ottonian period of the Pfalz was opened inside in 2004.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.
