(Marktstraat 13) is a large basilic cross church, with a five-sided closed choir with a choir hall and a large built-in tower of three sections with crenellated balustrade and eight-sided spire. From 1380 began the construction of the late Gothic choir of a single-nave cross church, whose nave and the late Gothic tower were completed in 1440.
From 1455 extensions were made: the choir aisle, extension of the transepts and extended side aisles. After a fire in 1468 the original plan of the aisles was changed. This can be seen in the pointed arch windows in the west facades of the side aisles that were originally higher, meant for half-wooden barrel vaults (exterior reconstructed 1978). After the completion of the church in 1479, the construction of the sacristy by Ydus van Eck followed. The church was once again plagued by fire in 1481 and 1490. In 1510 the church was restored. The tower contains a bell (circa 1450) cast by Steven Butendiic and has a spire (1661) made by A. de Heer. The church has been restored in 1935-'43 (L. Streefkerk) and 1965-'78. During the last restoration, the tower was given the task of tilting and the six-sided celebration turret, which was shot in 1672, was reconstructed. Furthermore, the tuff stone tower entrance has been completely renovated and the neo-Gothic portal (1860, 1949) has been demolished on the market side and the consistory of the choir has been rebuilt.
The interior is covered by a wooden barrel completed in 1510 with drawbars on display sets in the middle nave, transept and high choir. The side aisles and the choir aisle have stone cross vaults. Above the arches there is a sham trifle with shallow pointed arches. The pillars in the ship have leaf capitals, in the choir the capitals are decorated with carved monsters, animals, grape branches and human figures. The wall styles under the transept vault feature carved figures and carved consoles with heads. The consoles of the vault in the tower portal show the four Western church fathers. A mural with St. Christoforus is visible on the north wall of the tower (second half of the 15th century).
Particularly noteworthy are the extensive vault paintings on the wooden vault of the nave and choir, which were added in 1510-'18. Here biblical scenes are depicted within late-gothic frames (restored 1967-'75). The painters are possibly from the area of Jacob Cornelisz van Oostzanen and influenced by his woodcuts and those by Albrecht Dürer. On the north side, themes from the New Testament are depicted and on the south side the corresponding Old Testament prefigurations. On the vaulted surfaces, the drawbeams and the scrolls, there are also painted scrolls and spellbands, and the weapons and house brands of donors: the city, the guilds and prominent families. The emperor Charles V's coat of arms suggests that the Christ's Cross was bestowed by him.
The church contains a wooden choir fence (1531) with rich carving in early renaissance forms, possibly made by Gregory Wellemans or his pupils. The crowning with the coat of arms of Charles V is largely a reconstruction from 1978. The inventory includes a wooden choir fence (1626), a late Gothic and a 17th century pulpit, 17th-century gentlemen's houses - including a magistrates' bench (1623), a militia bank (1663) and an orphanage bench (1681) - and also a decalogical sign (1603) and a tailor and cloth shop (1618). A marble relief from 1773 by J. Poggeman (design J. Humbert) recounts the reconquest of Naarden in 1673 by Prince William III. The large organ in neo-Gothic cabinet was made in 1862 by C.G.F. White. The choir organ was built in 1937 by D. Flentrop for the World Exhibition in Paris with a by F.A. Eschauzier designed cabinet (transferred 1938).
