What geographical region is primarily associated with Incan art?

Incan art is most closely associated with the western side of South America, particularly in regions that are part of present-day Peru, Bolivia, and Ecuador. This geographical area was the heart of the Inca Empire, which flourished from the early 15th century until the Spanish conquest in the 16th century. The Incas developed a rich artistic tradition that encompassed various forms such as textiles, pottery, metalwork, and monumental architecture. Their art often featured intricate designs, bright colors, and symbolic representations reflecting their beliefs and cultural practices.

The western side of South America is also where the Inca constructed significant architectural feats like Machu Picchu and Cusco, both influential to the development of their artistic legacy. This region's diverse geography, including the Andes Mountains and the coastal areas, contributed to the various materials and techniques used in Incan art production. Therefore, it is this specific area that is directly linked to the cultural and artistic achievements of the Incan civilization.
