In the mountain range of the Andes in Peru, at over 3,700 meters above sea level, lies the Q'eswachaka suspension rope bridge, declared an Intangible Cultural Heritage of Humanity by UNESCO. The hand-woven bridge, which connects both sides of a gorge over the Apurímac River, has become the last remaining Inca bridge in use to survive modern times. This has been made possible through the transmission of Inca culture and engineering across generations, which renew the bridge every year to ensure its preservation.
