'Het Nieuwe Huys' (Westzijde 80) was built in 1687 for the Flemish Mennonites. The green-painted wooden building received plans from L.J. Immink a brick front building with two portals and a meeting room.
The interior is covered by a wooden vault with 19th-century decorative painting and has galleries on three sides. The church contains 17th century pews, two 18th century deacon boards and one by J.P. Künckel built organ (1782) with a richly carved cabinet with images.
