The masterpiece a privateer brought home
In 1473 Gdańsk privateers under Paul Beneke seized the San Matteo, a ship sailing from Bruges to Italy. In the cargo was a huge triptych by Hans Memling, The Last Judgement, painted for Angelo Tani of the Medici Bank's Bruges branch and meant for a chapel near Florence. It never arrived. The ship's owners gave it to St Mary's, one of the largest brick churches in the world, and it stayed there despite a long lawsuit from Italy.
Then everyone else wanted it. In 1807 it was taken to Paris for Napoleon's museum, where it was labelled as a Jan van Eyck. It came home through Berlin in 1817. In 1942 it was hidden from the bombing, in 1946 the Red Army found it and sent it to the Hermitage, and ten years later it came back to Poland.
The original belongs to the National Museum, 13 minutes on foot from the venue, but it is off display for conservation work and due back at the start of 2027. Until then, St Mary's has a copy, and you have a reason to come back.
St Mary's is open on weekdays 08:30-17:30, free. Climb the tower first: about 400 steps, 20 zł, closed in bad weather. Visitor information, map.
