AP —A big, round, 4,000-year-old stone building discovered on a Cretan hilltop is puzzling archaeologists and threatening to disrupt a major airport project on the Greek tourist island. Resembling a huge car wheel from above, the ruins of the labyrinthine, 1,800-square-meter (19,000-square-foot) building came to light during a recent dig by archaeologists. The building may have been used for religious or ritual purposes, the Greek Culture Ministry said. Greek Culture Ministry/APThe site was earmarked for a radar station to serve a new airport under construction near the town of Kastelli. Archaeologists don’t yet know what the hilltop structure was for.
