The Palaeologi Castle in Acqui Terme was mentioned for the first time in 1056. It was rebuilt in the 15th century by Marquis William VII of Montferrat.
Acqui Terme’s Archaeological Museum is housed inside the castle. The exhibition is divided into three sections (dedicated respectively to prehistory: from Palaeolithic to Neolithic, to the Bronze and Iron Ages, to the Roman period and finally the Middle Ages), with a tour that comprises a total of seven rooms, plus further spaces dedicated to temporary exhibitions. Many notable artefacts of great historical and archaeological interest are included, that altogether offer an insight and important testimonies to the uninterrupted human presence in the Acquese area, providing us with an overall vision of the city’s population, from remote times right up to the threshold of the modern era.
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.
