Arnot Tower is a ruined 16th-century castle. The current building dates from c. 1507, though fortifications were present c. 1400. The castle has four storeys and a vaulted basement. It was built by the Arnot family who have records dating back to 1105. David Arnot of Fyfe was one of 2000 noble landowners required to swear allegiance to King Edward I of England in 1296. Nicol Arnot Arnot was a loyal supporter of King Robert the Bruce. Robert Arnot was killed in the battle of Flodden in 1514. The Arnots abandoned the old tower around 1700.
In 1760 local poet Michael Bruce wrote a poem about the true story of a love affair between an Arnot daughter and a Balfour of nearby Burleigh Castle. The families were in a feud, and it is believed the daughter of Arnot eloped to Burleigh Castle.
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.
