Ongoing Archaeological Work in Galicia
In Spain, a team of archaeologists is investigating a one-of-a-kind petroglyph in Europe that depicts the layout of a hut covering around 40 square meters. This research is part of the fourth excavation campaign at Santa María Madalena de Adai, located in Lugo, Galicia. The campaign began on August 31, 2026, and is scheduled to conclude on September 18, 2026. The study focuses on petroglyphs, burial mounds, and rock shelters to better understand the prehistoric sacred landscape of the region.
Leading the project is Professor Pilar Prieto from the University of Santiago de Compostela (USC) and researcher at CISPAC. The team is examining two rock shelters in Penash do Caldeiru, including one known as Pena Travesa. The petroglyph at Pena Travesa features cup-shaped indentations on the rock's surface. Recent efforts have expanded the catalog with six new burial mounds and two additional petroglyphs.
Geophysical Techniques Set to Enhance Discoveries
Later in September 2026, geophysical surveys are planned to locate underground structures without immediate excavation. These non-invasive methods promise to streamline archaeological investigations and preserve the integrity of the sites.
This Spanish research gains additional significance when compared to discoveries elsewhere, such as the 2021 find by Canadian archaeologist Ernie Walker. He uncovered a petroglyph while observing bison herds in Wanuskewin Park. Reflecting on the find, Walker said:
“My heart was pounding because I wasn’t expecting this. The carving, known as the ribbed stone, resembles bison bones and symbolizes fertility.” - Ernie Walker
His experience highlights how careful observation is crucial to archaeological breakthroughs.
Overall, the ongoing investigations in Galicia are opening new avenues for understanding prehistoric cultures and their interactions with the environment. The petroglyphs and burial mounds discovered here offer valuable insights into social structures, religious beliefs, and ecological conditions of ancient communities.
By integrating advanced geophysical methods into their research, archaeologists in Galicia are pushing the boundaries of how we study and interpret the distant past, potentially reshaping our knowledge of early human societies.
