This is quite an important find which was only gradually realized as such. A large and well appointed, heavily Caravel which sank in 1495 in the Baltic. Notable for the fact that it had gun-ports, and this is a bit earlier than they were supposed to exist (this is something I have had big arguments about online – I have been told very aggressively that these didn’t exist until decades later, and then only in the Atlantic facing navies).
It appears to have been the first caravel built in the Baltic / North Sea zone. It is not, however, the first Caravel to be active in this region, that would probably be the Peter Von Dangzig, originally built in France and converted to a warship in the Danzig shipyards in the 1470s.
