    The Tannenberg, a German steamship sunk by a mine in 1941, offers a different kind of wreck dive off Bornholm. Lying at a uniform 13 metres, she’s completely broken up, more a field of debris than an intact vessel, which makes for an interesting rummage. We’ve found her twisted metal plates and exposed machinery provide plenty of nooks and crannies for local fish, especially cod and blennies, to hide amongst. While not a dramatic upright wreck, the Tannenberg is a fascinating historical puzzle, best suited for divers who enjoy piecing together a story from scattered remains. Visibility here can vary, so picking a calm day with good light really helps bring out the details.
