Marine archaeologists have identified a vast circular wooden structure preserved in the anaerobic mud of the North Sea floor. Utilizing high-resolution 3D seismic mapping, the team located the remains of 48 massive oak pillars. Similar in design to the famous Seahenge but significantly larger, the site suggests a major ceremonial hub once existed on the now-submerged landmass of Doggerland.
The preservation of the timber is attributed to the low-oxygen environment of the seabed silt. Researchers believe this Neolithic monument was once a terrestrial site used for sky burials or solar rituals before rising sea levels claimed the coast approximately 5,000 years ago. Further underwater excavations are planned to retrieve core samples of the wood for dendrochronological dating.
