The Treasure of Underwater Turku

Many people know about the archaeological excavations in the vicinity of Turku Castle, but few people know about the ancient plots of land under the Aura River. The latest breakthrough in excavations took place in Olavintie when it was discovered that the underwater treasure was accessible directly by submarine! The first signs suggest that the objects found date back to the golden age of Turku's history, almost 200 years ago... However, something about the excavations has shocked the Archaeological Society of Southern Finland: no one agrees to go to the excavations or talk about their contents anymore. How can something that old be so shocking? What does the underwater treasure of Turku tell you?
