Solza Castle probably dates back to the 10th or 11th century. Here was born the famous condottiere Bartolomeo Colleoni. According to tradition, when Bartolomeo Colleoni left Solza Castle, he was between 14 and 15 years old: little more than a boy, even for those times. No-one could have predicted then that he was destined to become one of the most famous condottieri of the fifteenth century.
Today the same castle appears rather insignificant with its modest fourteenth century plan, but it is still worth visiting the small village of Solza, near the river Adda, and use it as starting point for making a historical tour of the castles dotted over the Bergamo plain. Two great powers, the Duchy of Milan and the Republic of Venice, were long-term rivals in this border 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.
