Vrouw Maria
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 9 October 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.
