The Q'eswachaka Bridge spans the Apurimac River Canyon in Peru, and links two communities. Every year, the communities come together to replace last year’s rope bridge with a new one made of strong, new grass. They’ve done this for hundreds of years, from the time of the Inka, with the process handed down through generations. Watch how they do it.
