Hashizume-mon Tsuzuki Yagura
This building stood looking down ”the Hashizume-ichi-no-mon gate,” the main gate to Ni-no-maru, the second enclosure. It was a very important watchtower for the surveillance of people going from San-no-maru to Ni-no-maru through Hashizume Bridge and the Hahizume-ichi-no-mon gate. The connecting hole in the center of the building was used to move weapons and food to the second floor. The Hashizume-mon gate was built in the ”masugata” style, just like the Ishikawa-mon gate.
