Hidden in the green depths where light is scarce we find shipwrecks from times long past. More than 16,000 of them lie as reminders at the bottom of the Baltic Sea. They all have their own history – telling tales of human destiny and mortal tragedy. In environments like these where a rocky seabed is quite rare, sunken wrecks are also rapidly colonised by new life. Sea anemones, sponges and mussels take hold of what we humans once lost. Cod up to more than one metre in length and eerie conger eels find plenty of food and hiding places amongst the wrecks, some of which are centuries old.
