The hall of Tamasaki Shrine joins the main sanctuary and the worship hall in the gongen-zukuri style, a Chiba Prefecture-designated tangible cultural property. The town's booklet dates the present hall to 1687, and the main sanctuary was repaired and repainted in the Edo and Meiji periods. The shrine gave the town its name.
