Goryōkaku — meaning, literally, “five-point fort” — is a star fort in the city of Hakodate, Japan. The fortress was built by the Tokugawa shogunate in the mid-1800s to protect the Tsugaru Strait from a possible Russian invasion. Today, Goryōkaku serves as a park for the city’s 280,000 residents, as well as a national Special Historic Site and a hub for cherry-blossom viewing in the spring.
