Underwater archaeology: 31 fascinating wrecks discovered in Lake Constance
Things are exciting at Lake Constance at the moment! Since 2022, scientists from the State Office for Monument Preservation (LAD) have made a remarkable find using the most modern technologies as part of the “Wrecks and Deep Sea” project: 31 previously unknown wreck remains on the bottom of the water. AZ reports, that the researchers examined over 250 potential anomalies, of which 186 were examined in more detail.
Lake Constance, up to 251 meters deep at its deepest point, not only contains culturally significant treasures, but also modern remains such as pleasure boats. The discoveries provide valuable insights into maritime history and technology, with an almost completely preserved cargo sailing ship in particular standing out. For many, this is a real journey through time, which is made easier by the good visibility due to the low growth of quagga mussels.
Fascination with wreck research
The team led by Prof. Dr. Dirk Krausse and Dr. Julia Goldhammer turned over every stone or wooden barrel with the help of diving robots and special groups of divers. Among the finds, two larger metal ship hulls are also documented, which may belong to the legendary paddle steamers “SD Baden” and “SD Friedrichshafen II”. The latter entered service in 1909 and could carry up to 600 passengers before sinking in 1944. Tagesschau highlights that these finds not only shed light on shipbuilding technology, but also on the common goods transported by Lake Constance shipping.
A particularly fascinating detail is the discovery of a rubble field in which at least 17 well-preserved wooden barrels were found. However, a suitable justification for the origin of these barrels is still missing. Scientists therefore agree: there is still a lot that remains hidden that needs to be explored.
Outlook for the future
The “Wrecks and Deep Sea” project will continue to develop until 2027. It is clear that salvaging the objects found is not the priority. Rather, the focus is on the systematic documentation and evaluation of these underwater monuments. The Herder website reports that the results of the project will continue to serve as the basis for a comprehensive archaeological inventory in the future. This can revolutionize the entire field of underwater archeology!
With every discovery, Lake Constance becomes a true treasure trove of history. Who knows what stories the next finds will tell?
