The Metropolitan Area Outer Discharge Channel in Saitama, Japan is a massive flood-control tunnel system that is truly incredible to behold.

At over 25 meters tall and177 meters long, the Metropolitan Area Outer Discharge Channel first went under construction in 1992 and was only recently completed. The structure's purpose is to alleviate the heavy flooding that frequently hits Saitama, Japan by as much as 80 percent, but when not in use, it also serves as a popular place for tourists and sightseers.
