Kanazawa Castle served as the residence of the powerful Maeda lords from 1583 to 1869. Maeda clan was a feudal domain that ranks second to the Tokugawa clan as regards to wealth and size.
In the long run, it had survived a conflagration on 1759, and again on 1881. The original structures remaining is the castle's monumental gateway, the Ishikawa-mon gate.
The castle's notable features are the two turrets (Hishi and Tsuzuki Yagura) connected by a long storehouse called Gojukken Nagaya. The main castle keep wasn't rebuilt since 1602.
Adding beauty to the castle is the newly-built Hashizune-mon Gate and the Gyokuseninmaru garden.
