(Raadhuisstraat 61) is a late Gothic cruciform church with a five-sided closed choir and a roof rider. From this late Gothic church, choir and transept were completed in 1511, the nave in 1518. In the roof rider hangs a clock (1511) cast by Geert van Wou. The blind west facade has three small round windows (oculi) in the spout gable. The church was restored in 1959-'64 and 1988-2003.
The interior is covered by wooden barrel vaults with draw beams. The scales from under the crossing trusses come from the medieval church of Nieuwe Niedorp (demolished 1876). At the organ gallery (1871) is an organ from about 1520 with a 16th century organ case. The inventory also includes a Renaissance choir (circa 1560), a pulpit (1664), a Louis XVI-style duo (end of the 18th century) with copper baptismal arch (third quarter of the 17th century) and brass desk (1690), a men's bank and a draft portal (both 1648). The church contains the tomb of François van Bredehoff († 1721), Freeman of Oosthuizen. The tomb with Minerva statue and portrait medallion was made in 1723 by Jan Peter van Baurscheit sr. And jr. In marble and freestone (restored in 2002). Noteworthy are the twelve mourning boards for the Van Bredehoff family (1685-1785).
The cemetery is closed by a wrought iron gate between stone posts with pediments and garden vases (circa 1860).
