Iya Kazurabashi Bridge, Japan

No one knows who built the Iya Kazurabashi Bridge or the other sister bridges just like it, but some believe they were built long ago by a people that were trying to escape the Genji Clan. They were built for the specific purpose to easily cut them down so their enemies couldn’t cross. Not exactly a ringing endorsement for their structurally sound engineering.
