The reformed church of Sint Maartensdijk is a late-Gothic pseudo-basilica that has survived better than some of the other churches in the area. The church has a tower from the 14th century. Remarkable is that the western side of the lower half of the otherwise brick tower is clad with a light coloured natural stone. This was done in the second half of the 15th century, when also buttresses and a polygonal stairturret were added.
The original church was replaced in the 15th century. In c. 1400 the choir was built. At its north side, in c. 1420 a small chapel was built. Later that century this chapel was enlarged to become the current northern choir. In the same period the old nave was replaced by the current nave and side-aisles. The southern side-aisle was later extended with a sacristy.
