Archaeologists discover unique symbol and structures in Galicia, Spain

Archaeological excavations in Galicia, northwest Spain, have uncovered significant remains dating between the 1st century BCE and the 1st century CE. Researchers at Pico da Bandeira discovered a circular building approximately four meters in diameter and another structure featuring sophisticated stone flooring that likely served as tiles.

A notable find includes a piece of granite engraved with a triskelion—a curved, propeller-like shape—alongside mysterious markings that have puzzled researchers. While the decoration might be a chain-like motif common in Roman antiquity, its exact meaning remains unclear. The discovery has surprised the excavation team, as the site was not initially expected to hold such significant structures.

Separately, genomic research published in ‘Science Advances’ by a team including the University of Vienna has revealed evidence of long-distance genetic exchange among Gravettian hunter-gatherers approximately 30,000 years ago. The study suggests that despite distinct regional groups, there was previously undetected gene flow between western and eastern European populations during the Upper Paleolithic period.
