The shipwreck named Bispevika 20 was first discovered in the middle of June, and the excavation took place in the following weeks. As the number in the wrecks name indicate, this is the twentieth shipwreck found in the northeastern part of Bjørvika. The name Bjørvika has existed since medieval times, and derives from the close proximity to the bishop’s residence in the old part of Oslo.
Bispevika 20 was discovered in direct connection to a timber raft, probably the fundaments and the only remnant of a pier that was constructed here in the mid-16th century. The pier is probably a continuation of the large harbour area excavated on the sites named Barcode B11-B12 and B3-B7, to the north of this year’s dig. All finds in the layer surrounding the wreck is dated to the 16th century, which indicates the wrecks age.
