Stach’s Bridge (vel “Most Mocarza”, “Mighty Man’s Bridge”) in Poland is the world’s largest bridge built by one man – 13 m tall, 20 m long, 7,5 m wide. Built in three years by 53-year old farmer Jan Stach, using his own hands as building tools, and his cow as the means of transporting the boulders. /u/WillManhunter /r/videos
