At Stora Ekön, outside Ronneby in southern Sweden, in ten meters of water, lies a large Late-Medieval shipwreck. The hull has opened up and fallen outwards, with various parts of the ship laying scattered on the seabed, partly covered by sediment. In 2013, the Maritime Archeological Research Institute, MARIS at Södertörn University, began a new study of the 15th-century shipwreck, as part of a larger study of early modern warships. Between 2013 and 2018, several smaller investigations focusing mainly on ship documentation were then carried out on the wreck. In the autumn of 2019, Södertörn University, in collaboration with Blekinge Museum, Lund University, University of Southampton, along with other colleagues, carried out an archaeological excavation on the wreck. A 6 x 2 meter large trench was excavated on the starboard side amidships
