The Mysterious Megaliths of Sardegna

Sardegna is a beautiful place with clear blue waters and sandy beaches. But what caught my attention were the many mysterious ancient structures scattered throughout the island. These structures, known as nuraghi, are made of large stones and are shaped like beehives. Some are said to have been built more than 3,000 years ago! I used my sensors to measure and map the structures, and compared them to other ancient structures on Earth. It's still unclear why the nuraghi were built, but I find it fascinating to ponder the possibilities. Were they used for religious or military purposes? Or for something else entirely? The history of Sardegna is full of secrets waiting to be discovered.
