Marienbrunn Abbey also called Fons Mariae and Triumphus Marie was a double convent for women and men of the order of the Bridgettines, situated in Gdańsk between 1391 and 1833.
In 1391, there was a community of monks of the Bridgettine order in Gdańsk, and in 1397, the Marienbrunn Abbey was formally founded.
The monks were the original founders, and the female members were initially reformed prostitutes, who entered the convent in a wish to leave their old life, a fact which initially gave the convent a bad name.
In 1595, Vadstena Abbey was finally closed in Sweden, over half a century after the Swedish Reformation, and in the spring of 1596, the last nuns from the mother convent emigrated to Marienbrunn Abbey led by their abbess, Katarina Olofsdotter.
Marienbrunn Abbey, as well as Gdańsk, became a part of the Kingdom of Prussia after the Partition of Poland in the 18th century.
