Since 2015 archaeologists from Blekinge Museum have been, excavating a site in Ljungaviken in Sölvesborg, Sweden. The experts have found at least 51 structures at what they believe was a coastal settlement that dates to the Stone Age ( Mesolithic). Their digs have revealed pits, hearths and postholes.The project is the largest archaeological project ever conducted in this part of the country. In the Blekinge Museum report , Carl Persson of the Blekinge Museum explains that “a sudden and violent increase of the sea level flooded the area with mud” and this helped preserve this archaeologically important area.
