Moat south of the main bailey

Archaeological surveys have led to the discovery of remnants of a moat, which cannot be seen in picture diagrams. On the left is a photograph of a cross section of the moat remnants. The moat measured approximately 10 meters wide, and can be restored to about 3 meters in depth. Excavated artifacts are from the second half of the 16th century, so it is believed that the moat was dug when Ieyasu was lord of Hamamatsu Castle, and it was filled with earth once more in the Edo Period.

Roof tiles account for the majority of excavated artifacts related to Hamamatsu Castle in the Edo Period. Some of the tiles are decorated with the family crest of the feudal lords who were lords of the castle. Family crest tiles of successive castle lords have been excavated at Hamamatsu Castle, so it is believed that the buildings were renovated or rebuilt throughout the Edo Period.

Artifacts excavated from Hamamatsu Castle town

In the downtown area of Hamamatsu City, there are buried traces of the castle town built from middle ages to the early modern period. The formation of the castle town of Hamamatsu Castle dates back at the very latest to second half of the 16th century, when Tokugawa Ieyasu used Hamamatsu Castle as his base of operations.
