It is a late 12th century Romanesque church with a 19th-century facade.

Over time the church was several times changed/converted but the North wall, South wall and choir show still beautiful signs of the Romanesque tuffstone church.

[1] The church is located on the Canterlandseweg 63[2] and was once a Roman Catholic church dedicated to Saint Martin but became a Protestant church after the protestant reformation.

It is listed as a Rijksmonument, number 35654 and is rated with a very high historical value.
