Braided over raging rivers and yawning chasms, these skeins of grass helped connect the spectacular geography of the Inca empire: its plains and high peaks, rainforests and beaches, and—most importantly—its dozens of distinct human cultures. It will be strung on the National Mall parallel to 4th Street Southwest, between Jefferson and Madison Avenues, where it will hang from several decorated containers in lieu of vertical cliff faces and hover—at its ends—16 feet above the ground. It should be able to hold the weight of ten people. For native Peruvians, traditional bridge-building is an important tie not only to new people and places, but also to the pre-colonial past.

  • Inca rope bridges are simple suspension bridges over canyons and gorges and rivers pongos constructed by the Inca Empire.
  • Every year, rural communities in Peru carry out an ancient tradition that stems back to the age of the Incan Civilization.
  • Bridges of this type were useful since the Quechuas did not use wheeled transport, Inca Rope Bridge Day trip, shows you a great knowledge of the Quechua people in terms of engineering as well as the hidden wonders of Cusco.
  • In the rugged, gorge-filled terrain of the Andes Mountains, there are places where roads alone would fail to provide adequate transportation.

In the rugged, gorge-filled terrain of the Andes Mountains, there are places where roads alone would fail to provide adequate transportation. But, as was the case with most obstacles they encountered, the Incas had a solution: bridges. Unlike the arched stone bridges built in Europe at the time, the Incas used rope to construct suspension bridges across mountain chasms, as they had long been experts at weaving materials from natural fibers.

Since there were no wheeled vehicles, the rope bridges worked beautifully for foot traffic, conveying both man and beast with ease. During bridge construction, large rope cables were formed from smaller ropes woven from llama and alpaca wool, as well as from grass and cotton. These were attached to stone structures on either side of the crossing.

More of the thick cables were stretched to form handrails as well as the floor of the bridge, which was then covered with wood and sticks. Longer than any stone bridge in Europe at the time, the Incan bridges spanned openings of at least feet 46 meters.

Travelers often crossed in the morning, as strong winds later in the day could cause the bridges to swing wildly like hammocks.

Because the materials that created the bridges were organic and biodegradable, they had to be rebuilt every year. Often, communities living near the bridges carried out this function. All of the Incan rope bridges are now gone -- except for one. Near the town of Huinchiri, Peru, one bridge remains, and it's rebuilt every year in a festival that lasts for three days.

People from nearby villages harvest the grasses that grow on either side of the bridge and each family weaves them into a meter yard length of rope. These smaller ropes are twisted into larger cables, which are then stretched over the Apurimac River. Then the Keshwa Chaca bridge is renewed for another year, as it has been for five centuries.

The Inca Rope Bridge That's Woven Across a River Each Year

As much as maize, or mountains, or llamas, woven bridges defined pre-Columbian Peru. Braided over raging rivers and yawning chasms, these skeins of grass helped connect the spectacular geography of the Inca empire: its plains and high peaks, rainforests and beaches, and—most importantly—its dozens of distinct human cultures.

It should be able to hold the weight of ten people. For native Peruvians, traditional bridge-building is an important tie not only to new people and places, but also to the pre-colonial past.

His own son is now learning the techniques from him, the latest in an unbroken bloodline of chakacamayocs that Arisapana says stretches all the way back to the Incas, like a hand-twisted rope.

The Incas—who, at the height of their influence in the 15th century, ruled much of what is now Peru, Ecuador, Argentina, Bolivia and Chile as well as parts of Colombia—were the only pre-industrial American culture to invent long-span suspension bridges. The Inca likely rigged up or more of the bridges across gorges and other previously impassable barriers, according to analysis by John Ochsendorf , an architecture scholar at the Massachusetts Institute of Technology.

Though anchored by permanent stone abutments, the bridges themselves had to be replaced roughly every year. Some of them were at least feet long and could reportedly accommodate men marching three abreast. Ochsendorf believes that Inca bridges may have first been developed in the 13th century. The bridges allowed for many Inca military victories: Inca commanders would send their strongest swimmers across a river so building could begin from both sides. But the exquisite structures apparently so dazzled some neighboring tribes that they became vassals without any bloodshed.

The invading Spanish were similarly amazed. European bridge-building techniques derived from stone-based Roman technology, a far cry from these floating webs of grass.

No wonder some of the bravest conquistadors were said to have inched across on hands and knees. Ultimately, the bridges—and indeed, the whole meticulously maintained Inca roadway system—facilitated the Spanish conquest, especially when it became clear that the bridges were strong enough to bear the weight of horses and even cannons. Some of traditional grass bridges remained in use until the 19th century.

It is one of just a handful remaining. The old bridge stands near a modern long-span steel bridge, built in the late s and typical of the sort that eventually made the Inca bridges obsolete. Therefore, we cannot allow our bridge to disappear. The grass is harvested just before the wet season, when the fiber is strongest. It is kept damp to prevent breakage and pounded with stone, then braided into ropes of varying thickness.

Sometimes, to test the ropes on site, workers will see if they can use it to hoist a hog-tied llama, Valencia says. To do everything by himself would take Arisapana several years, but divided among community members the work takes only a few days.

The old Inca bridge style differs from more recent versions. In modern suspension bridges, the walkway hangs from cables. In Inca bridges, however, the main cables are the walkway. These large ropes are called duros and they are made of three grass braids each. The handrails are called makis. Shorter vertical ropes called sirphas join the cables to the railings and the floor of the bridge consists of durable branches. The bridge on the National Mall will be made of hundreds of ropes of varying thicknesses.

The math involved is formidable. They test the strength of the rope, every piece has to go through quality control, and everything is handmade. Even for those fully confident in the math, crossing an Inca rope bridge requires a certain courage. Even tourists from other countries visiting his remote village know to not to approach the bridge empty-handed.

The bridge builders—who are accustomed to receiving curious visitors back home, but who have never traveled to the United States—are pleased that their ancient craft is carrying them to new lands. Continue or Give a Gift. Privacy Policy , Terms of Use Sign up.
