Cromeleque dos Almendres
About
The Cromlech of the Almendres, located in the Alentejo region of Portugal, is one of the largest and most extraordinary megalithic sites in Europe. Dating back to as far as 6000 BC, the complex consists of a series of stone circles and free-standing menhirs arranged in concentric patterns that hint at an early attempt to understand and celebrate the cosmos. Archaeological research has identified three distinct construction phases—Early, Middle, and Late Neolithic—each building upon the earlier layout. The earliest monoliths form a central circle of roughly 30 granite shafts, while later additions create double ellipses and even a star‑shaped circle that may have served as a solar observatory. The stones exhibit carved motifs and alignments that correspond with the equinoxes, suggesting that the Almendres group was used for seasonal ceremonial purposes. Today visitors can walk among the standing stones, following a mapped path that reveals the purposeful geometry and the relationships between the different concentric formations. The site is free to enter, making it an accessible and educational destination for archaeology enthusiasts, families, and travelers seeking a glimpse into Europe’s distant past.
