Island

The Incas lived on a remote Peruvian Island of Taquile surrounded by the Great Lake Titcaca. Its landscape consists of many mountains and churches and temples. In the incan language, Quechua, their empire was known as Tawantinsuyu. "This means "land of the four quarters."  The empire and all four of the quarters which it was divided into met at the Incan capital Cuzco, Peru in South America (Ogburn, 1998).  Today, pieces of the Incan empire still remain in different areas of the central highlands of the Andes.  The Incas were a vast group, and the strongest of this were located in the highlands.  By 1532 they had an accumulated mass of land that spanned from the Pacific coast across the Andes to the Atlantic coast and from central Chile to Ecuador."
