Pre-Columbian Architecture
Mesoamerican architecture
Mesoamerican architecture is the set of architectural traditions produced by pre-Columbian cultures and civilizations of Mesoamerica, traditions which are best known in the form of public, ceremonial and urban monumental buildings and structures. The distinctive features of Mesoamerican architecture encompass a number of different regional and historical styles, which however are significantly interrelated. These styles developed throughout the different phases of Mesoamerican history as a result of the intensive cultural exchange between the different cultures of the Mesoamerican culture area through thousands of years. Mesoamerican architecture is mostly noted for its pyramids which are the largest such structures.
One interesting and widely researched topic is the relation between cosmovision, religion, geography, and architecture in Mesoamerica.

Much seems to suggest that many traits of Mesoamerican architecture were governed by religious and mythological ideas. For example, the layout of most Mesoamerican cities seem to be influenced by the cardinal directions and their mythological and symbolic meanings in Mesoamerican culture.
Another part of Mesoamerican architecture is its iconography. The monumental architecture of Mesoamerica was decorated with images of religious and cultural significance, and also in many cases with writing in some of theMesoamerican writing systems. Iconographic decorations and texts on buildings are important contributors to the overall current knowledge of pre-Columbian Mesoamerican society, history and religion.
Incan architecture
Incan architecture is the most significant pre-Columbian architecture in South America. The Incas inherited an architectural legacy from Tiwanaku, founded in the 2nd century BCE in present day Bolivia. The capital of the Inca empire, Cuzco, still contains many fine examples of Inca architecture, although many walls of Inca masonry have been incorporated into Spanish Colonial structures. The famous royal estate of Machu Picchu is a surviving example of Inca architecture. Other significant sites include Sacsayhuaman and Ollantaytambo. The Incas also developed an extensive road system spanning most of the western length of the continent.
