This park symbolizes the people of Toyohashi, and it is an oasis of the town, as it includes the ruins of Yoshida Castle, an art museum, an assembly hall located on the outskirts of the castle, and other cultural facilities. The area of the park is 21.6 hectares, and the area of land of the city hall, which neighbors the entire park, touches the ruins of Yoshida Castle. Since the Meiji Era, military units of the old Japanese armed forces had been stationed there and part of that visage has been preserved; therefore, you can enjoy various aspects of the ruins.
