UN designates Inca road network in Peru and 5 other countries as World Heritage site

The United Nations has designated parts of the road network used by the Inca empire as a World Heritage site.

The U.N. Education, Scientific and Cultural Organization granted the designation Saturday during a meeting in Doha, Qatar.

Peru's Culture Ministry says the network known as Qhapac Nan extends nearly 60,000 kilometers (37,000 miles). It spans the length and breadth of the Andes mountain range in six countries.

While parts of it pre-dated the Inca empire, the network reached its maximum expansion in the 15th century as the culture celebrated for architectonic prowess used it to exert dominance over the Andes.

Peru, Argentina, Chile, Bolivia, Ecuador and Colombia combined to nominate the road network, only portions of which were granted Heritage Site status.

Much of is in disrepair, covered by vegetation.
