Sümeg Castle was built in the latter half of the 13th century by Béla IV of Hungary. It is situated atop a mountain called 'Castle Hill'. Later, it was presented as a gift to the Roman Catholic Archdiocese of Veszprém by Stephen V of Hungary. In the 15th century, the castle was fortified, and the second of two towers was built.In 1552, in response to the capture of Veszprém by the Turks, the castles was rebuilt and fortified to serve as a frontier fortress. In 1713, after the Austrian occupation during Rákóczi's War for Independence, troops set the castle on fire.
Today, the castle is the main tourist attraction for visitors to Sümeg. Since 1989, it has been privately held. It was restored on a large scale, and is now operated as a tourist attraction, providing events and tournaments. It is considered to be Hungary's most well-preserved fortress.
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.
