No.917 Once upon a time

The photo shows foundation stone remains, which you might miss if you're not paying attention. There is an information board nearby. Please look for it. The Mita Aqueduct was created by diverting water from the Tamagawa Aqueduct in the 4th year of Kan'ei (1664) to meet the water demand in the Edo city area. Initially used as drinking water, it was later used for agricultural purposes, but was abolished in 1974 due to declining usage.
