The castle was originally built on a site that served as a coastal fortification point during the Warring States period.
The castle underwent massive reconstruction by Todo Takatora, a renowned master of castle architecture who implemented sophisticated defensive wall designs.
The original main keep was destroyed by fire in 1612 and was never rebuilt during the Edo period.
The site contains a statue of Todo Takatora, the primary architect of the site's most recognizable features.
During the Meiji Restoration, most castle buildings were dismantled, leaving primarily the stone base and earthen mounds.
Tsu Castle Ruins, also known as Anotsu Castle, features stone walls and water moats dating back to the late 16th century. Originally constructed by Oda Nobunaga's brother, Nobukane, the site was later significantly expanded by Todo Takatora. The current structure consists of reconstructed turrets, gates, and meticulously maintained gardens within the Oshiroyama Park area. It is recognized for its seasonal vegetation, particularly cherry blossoms in spring and autumn foliage. The site highlights the structural evolution of Japanese fortifications from the Azuchi-Momoyama period through the Edo period. Visitors can explore the remnants of the inner bailey and the existing stone foundations that once supported a massive keep.
