Shiomi-zaka-mon gate of Edo Castle

 In the East Gardens of the Imperial Palace, there is a slope called shiomi-zaka slope is between the main enclosure and the second enclosure, and there was a gate called Shiomi-zaka-mon gate at the top. There was a turreted passageway (called Watari-Yagura-mon) on the right. Only stone walls remain now. The stone walls had perfectly cut stones, fit tightly together and the surface was smooth. But in 1863, the gate was burned by the Great fire, so the stone walls got lumpy. They are covered by wire netting for safety now.

 A moat called Shiratori-bori moat is on the left side of the slope. Stone walls of the moat were built around 1606. They are older than the stone walls of the gate, it is rough field stone style (called nozura-zumi). The stones do not fit tightly together, and the surface is not smooth.
