The Qhapaq Ñan, often referred to as the Great Inca Road, was a sophisticated transportation network, primarily built by the Inca Empire.
Stretching over 30,000 kilometres, it traversed many kinds of terrain, from the snow-capped Andes to the dense Amazon rainforests.
The ingenuity of Inca engineers was evident in their ability to adapt the road to various landscapes, utilising a range of materials and techniques to ensure durability and efficiency.
Key engineering feats included the construction of suspension bridges across vast river gorges and the use of massive stone slabs to pave paths through rugged mountainous regions.
