In 1969 an interesting and unique shipwreck was found at lot U 34 in the polder of eastern Flevoland, the Netherlands. The ship, dated about AD 1530, was 30 m long and completely clinker-built. The overlapping strakes were connected by a combination of rove and rivet and small treenails. In the Netherlands a few similar clinker-built shipwrecks have been found dating from the same period, but not as large as the ship at lot U 34.
