Isla del Sol

Isla del Sol is an island in the southern part of Lake Titicaca. It is part of the modern Republic of Bolivia. Geographically, the terrain is harsh; it is a rocky, hilly island. There are no motor vehicles or paved roads on the island.

The Aymara name for the island is "Titi'kaka". It is not known what was the original meaning of this word. Some linguists and archaeologists believe the name to be a corruption of "Titi" (puma) and "Kala" (rock). In the 1612 Aymara-Spanish dictionary of Ludovico Bertonio, the phrase "Tahksi kala" is listed as "piedra fundamental" or "foundation stone" possibly alluding to the origin story of the Inca that the Sun and Moon were born in the lake.

The main economic activity of the approximately 800 families on the island is farming, with fishing and tourism augmenting the subsistence economy. There are over 180 ruins on the island. Most of these date to the Inca period circa the 15h century AD. Archaeologists have discovered evidence that people lived on the island as far back as the third millennium BCE. Many hills on the island contain agricultural terraces, which adapt steep and rocky terrain to agriculture. Among the ruins on the island are the Sacred Rock, a labyrinth-like building called Chicana, Kasa Pata, and Pilco Kaima. In the religion of the Incas, it was believed that the sun god was born here.
