The stone spheres of Costa Rica, often hailed as the “mysterious stone spheres,” are a collection of over 300 perfectly spherical stone balls scattered across various locations in the country. Ranging from a few centimetres to colossal sizes exceeding two meters in diameter and weighing up to 16 tons, these artifacts are attributed to the ancient Diquis culture, flourishing in the region from 600 to 1530 AD.

What is their purpose?

The purpose and meaning of the stone spheres remain subjects of ongoing debate among archaeologists and researchers. Theories range from astronomical and ceremonial functions to architectural or structural roles. Some propose practical applications, like marking water sources or delineating territorial boundaries.

Symbolism?

Many believe the spheres served as status symbols, reflecting the wealth and power of individuals or communities. This is often tied into the notion that they represented markers for ritual or ceremonial use tied into a complex cosmological an/or religious belief system.

Their purpose may not be agreed upon in scientific circles but what has been agreed to are their cultural importance. They have been designated a UNESCO World Heritage Site (2014).
