Marking the start of the sailors' quarter, or 't Schipperskwartier, is St Pauluskerk. The proud, white Gothic church (1517) was built for the Dominicans. It suffered over the years due to fires, the latest in 1968 when locals rallied to save the art treasures inside. The baroque interior is resplendent with a stunning procession of wooden confessionals and carvings, altars, a (partly) ancient organ and marble embellishments, as well as paintings by the 17th-century masters and lesser artists.
