Vrouw Maria ("Lady Mary") was a Dutch wooden two-masted merchant ship carrying a valuable cargo of art objects, captained by Raymund Lourens, that sank on October 9, 1771, in the outer archipelago of the municipality of Nagu, Finland, 11 kilometers south-east of the island of Jurmo. In 1999, the ship was discovered by the members of Pro Vrouw Maria, led by Rauno Koivusaari. A dispute between the discoverers and the authorities was later resolved. The ship was in good condition when it was discovered, but only six objects from the deck of the ship have been salvaged. The cargo holds have not been disturbed, so the condition of any art on board remains unknown. The Finnish National Board of Antiquities is responsible for the ship and all recovery efforts.
