A road system built by the Inca Empire has been granted World Heritage status by the United Nations cultural agency, Unesco.
The Qhapaq Nan roads go through six South American countries.
It was built in the most diverse terrains, linking communities in the Andes mountains to fertile valleys, rainforests and deserts.
Unesco described the system as an engineering wonder that must be restored and preserved.
The Andean Road System was built over hundreds of years and was used by the Spanish when they arrived in South America in the 16th Century. It was used mostly for trade and defence.
It covers some 30,000 km (18,600 miles), from modern-day Colombia in the north to Argentina and Chile in the south, via Peru, Ecuador and Bolivia...
