Niches (仏龕) open on all four sides of the second tier, and a pit at the top held a ceramic cylindrical vessel among other things; the vessel is now at Tenri Sankokan in Nara. It is thought to be a Buddhist pagoda of the Nara period.

02 / Tawara Canal Aqueduct and Hyakken Stone Channel (田原用水水路橋と百間の石樋)

A stone aqueduct carried the Tawara Canalacross the Onoda River and westward.

In the Genroku era, under Tsuda Nagatada, a senior retainer of the Okayama domain, a stone aqueduct was planned over the Onoda River to extend the Tawara Canal west. The aqueduct (Ishi no Kakehi, 石の懸樋) is 12.96 m long and now stands restored in a memorial park. Downstream, the Hyakken Stone Channel (百間の石樋) is a stretch cut through rock about 180 m long to carry water.

The top of the mound has not been surveyed, and the city says the final stage of construction may not have been carried out. The moat was reworked and reused as an irrigation pond in the Edo period.
