Machu Picchu has two sectors; an agricultural sector and an urban
sector. The agricultural sector consists of stepped terraces for
cultivation (andenes) built on the slopes of surrounding mountains .
The urban sector is "U" shaped and has two immense architectural
groups with streets and stairwells that consist of a total of 3,000
steps, as well as a network of water canals suitable for domestic
and irrigation use, interspersed with small squares and courtyards.
