A Unique Location

Some researchers consider this one of the world’s highest navigable lakes. But this isn’t the only thing that makes it a spectacular site. Historians have proven that during the 15th and 16th centuries, this lake was an important pilgrimage site for the Incas.

That Holds A Historical Significance

According to ABC News, scientists have discovered animal bones, a stone anchor, in addition to various ceramic bowls, vessels, and tools that prove that a settlement thrived near this location. However, the submerged nature of the site makes it more challenging to study.

Puzzling Islands

Many islands on Lake Titicaca played a significant role in Inca mythology. For example, Isla del Sol is considered the birthplace of the founder of the Inca civilization and the home of the Sun God. This probably explains why the lake was regarded as sacred.

But They Aren’t Confirmed Yet

The use of large stones and exceptional workmanship are telltale signs of artifacts related to the Tiwanaku culture. These are quite distinct from Incan masonry. However, future explorations may reveal more about the people who built these structures.

Bizarre Artifacts

The Fuente Magna is a peculiar finding. It’s a large stone vessel, but its purpose and the details of where it was found remain uncertain. However, what makes it incredibly puzzling is that some of the inner engravings resemble non-Sumerian Mesopotamian cuneiform writing.
