According to ancient texts, Binicodrell was a large Talayotic period settlement (1000-700 B.C.). Today, only two talayots remain, of which the northern one is in a better condition; it has a zigzag shaped access ramp leading inside, although researchers disagree on whether it was built at the same time as the talayot. The southern talayot, on the other hand, is quite dilapidated.You can still find fragments of pottery on the ground, dating from various eras: Talayotic, late Punic, Roman and Islamic. Inside the protected area of the site there is a necropolis.
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.
