The first star-shaped western citadel in the country. A home base consisting of a stone wall and an earthwork is arranged at the five corners, and a low base built with the stone wall and the earthwork is also built on the outside of the basement. The largest feature is that it is not a Japanese castle with tall walls that had been the mainstream in Japan until then, and its height was suppressed. This was a forged castle style devised in France in the 16th century to accommodate the firearms that emerged and flew in all directions.
There is only one place protruding like an arrowhead "Half Moon Fortress" at the main entrance. The bastion eliminates blind spots and allows to efficiently intercept and shoot enemies.
From the New Goryōkaku Tower (107m high) completed in 2006, you can enjoy the whole view of Goryōkaku, which is invisible from the ground, including five bastions and one half-moon basin.
