Historians believe the Inca began building Machu Picchu around the 1450s, but because they left no written records behind, no one knows exactly what their purpose was. Machu Picchu was built in the classical Inca style, with polished dry-stone walls.

历史学家认为，印加人在1450年代开始建立马丘比丘，但是因为他们没有留下任何文字记载，所以没有人确切地知道他们的目的是什么。马丘比丘的建筑具有印加传统风格——抛光干石墙。
