Monte d’Accoddi

Monte d'Accoddi is an archaeological site located in the region of Sardinia, Italy. It is a unique and enigmatic structure that combines elements of both megalithic and proto-historical architecture.

The site consists of a large earthen platform, measuring about 57 meters in diameter and 5 meters in height. The platform is accessed by a monumental ramp on the eastern side, which leads to a paved area at the top of the platform. At the center of the platform is a raised rectangular structure, made of large stone blocks, which is thought to have been a ceremonial altar or a place of worship.

The platform and altar structure at Monte d'Accoddi are unique in the Mediterranean region, and have no obvious parallels with other known megalithic or proto-historical structures. The site's purpose and function remain a mystery, although various theories have been proposed over the years.

One theory suggests that the platform and altar structure were used for astronomical observations or rituals related to the cycles of the sun, moon, and stars. Others have suggested that the site was used for political or economic purposes, such as a meeting place for local chiefs or a center for trade and exchange.

Excavations of the site have uncovered a range of artifacts and objects, including pottery, stone tools, and animal bones. The artifacts provide some clues about the site's age and history, although its exact chronology remains uncertain.
