Dated to 23,000 years ago, it predates Egypt's Great Pyramid by over 18,000 years. In 2025, after nearly a decade closed to the public, Theopetra Cave reopened. The timing coincides with new research published in 2026 by Dr. Nina Kyparissi-Apostolika who has led excavations at the site since 1987. The wall, discovered decades ago, was built during the Last Glacial Maximum, a period of extreme cold when much of Europe was blanketed by ice. Researchers believe early humans constructed it to partially seal the cave’s entrance, blocking freezing winds. Located near Kalambaka in central Greece, Theopetra Cave offers a continuous archaeological record spanning 130,000 years, making it one of Europe’s most significant prehistoric sites. Excavations have uncovered layers of occupation from the Middle Paleolithic to the Neolithic peri...
