The wreck was found on the depth of 42 meters. The construction has been completely destroyed, but there was still over 40 cast iron cannons laying on the seabed. The finding is not only very interesting from the archaeological point of view, but it also has a great antiquarian value. The cannons were produced in Sweden in 1771. The thorough research will be provided within the nearest months. Moreover, during the expedition, the crew has found another wreck with pottery, navigational instruments, glassware and stoneware, probably from the 17th century. Lifting the monuments and transferring them for conservation is only one of the elements of the whole marine heritage protection process. This time the decision was to place some of the cannons in the underwater museum next to the ‘Solena’ wooden wreck from 17th century. All of the actions connected with the research and transferring the finding to the Gdańska Bay are being conducted according to the recommendations of Pomeranian Regional Monument Conservator. Placing the cannons in the underwater museum will not only make the sightseeing more attractive, but will also help to protect them until the conservation process.
