Inca Cuzco was different in concept and plan from European cities.
It was designed in the form of a puma, with the 15th-century
fortress of SACSAHUAMAN as the head. The confluence of the Huatanay
and Tullumayo rivers was canalized and straightened to form the tail.
The core of the city contained official and ceremonial buildings and
residences of ruling officials. Many other buildings and residences
were dispersed at a considerable distance in the countryside
surrounding the core, but they were defined as part of the capital.
The Inca capital
is especially known for its architecture of enormous cut-stone
blocks fitted so perfectly that no mortar was needed. Coricancha,
the temple of the sun, and the fortress of Sacsahuaman are the most
outstanding examples of this type of construction
