Endangered species who find a habitat in the archipelago include Osmoderma eremita and Lecanographa amylacea.
The latter, having been founded as a naval base, is noted for its Baroque architecture and listed as a UNESCO World Heritage Site.
Shipbuilding has been a traditional local trade within the archipelago and the area is known for a traditional type of small boat, called blekingeeka and used for tasks like fishing and transporting stone locally.
[3] In the 1970s, the local diving club discovered a shipwreck in the Blekinge archipelago that was eventually identified by archaeologists as Gribshunden, a 15th-century Danish warship.
[4][5] The shipwreck is significant as one of the best-preserved wreckages from the early modern period.
