A Timeless European Emblem
During archaeological excavations at the Castro do Pico da Bandeira site in Galicia, Spain, researchers discovered a granite stone engraved on both sides. One face displays a triskelion—a symbol made up of three spiraling arms rotating counterclockwise from the center. The stone’s reverse side bears a rough petroglyph whose meaning remains under investigation. This remarkable find was uncovered within the remains of a large circular structure dated between the 1st century BCE and the 1st century CE.
Ongoing Excavations and Key Artifacts
Excavation efforts at Mount Torroso near A Guarda resumed in 2022 after nearly a century-long hiatus. The current dig phase began in 2025, supported by the Salsidos community landowners’ association. Archaeologists have been studying this area intensively, revealing a range of significant artifacts, including:
- Stone slabs
- Fragments of Roman amphorae
- Orthogneiss objects of unknown purpose
It’s important to note that more than half of the circular building has yet to be excavated.
Archaeologist Benito Vilas explained that the team initially noticed engravings on one side of the stone, with the triskelion only becoming visible after flipping it over. He also drew parallels between this discovery and a similar stone from an Iron Age bathhouse in Britiresh, Portugal, which features a petroglyph on its back as well. The Castro culture, which thrived in this region during the Iron Age and Roman periods, frequently incorporated the triskelion symbol in their artistic expressions.
Excavations are ongoing, with researchers hopeful that future findings will shed further light on the lives and beliefs of this ancient civilization.
The unearthing of this granite stone engraved with a triskelion and petroglyph in Galicia represents a significant advancement for archaeology, offering valuable insights into the cultural and spiritual world of the region’s early inhabitants. The triangular triskelion motif, widely used by the Castro culture, highlights connections across different European civilizations and opens new avenues for exploring their interactions. Continued excavation is expected to reveal more about the daily life and religious practices of these historic communities.
The recent discovery of the granite stone in Galicia adds to the rich tapestry of archaeological finds in Spain, particularly in relation to the Iron Age. For those interested in similar historical revelations, the uncovering of a significant Iron Age wall beneath a Roman settlement on Ons Island offers fascinating insights into the region's ancient past.
