Reformed Dutch Church of Blawenburg, now known as Blawenburg Reformed Church, is a historic church at 424 County Route 518 in the Blawenburg section of Montgomery Township in Somerset County, New Jersey. The Blawenburg Reformed Church Cemetery is located on County Route 601 near CR 518.[2] The church was added to the National Register of Historic Places on July 22, 1985 for its significance in architecture and religion.[3] It was added as a contributing property to the Blawenburg Historic District in 1990.
Construction of the church building started in 1830 and was completed in 1831. Richard Brown was the chief carpenter. It was then known as the Second Dutch Reformed Church at Harlingen. It then became the Reformed Dutch Church at Blawenburg on March 4, 1832.[4] A schoolhouse was built in 1853 by the church. It is now the village preschool. The church cemetery is west of the church on land partly donated by John Van Zandt in 1859.[3]
The church is a two story white building, an example of late Georgian architecture. It has a bell tower with a feather-shaped weathervane on top. The facade features an oculus and two pie-shaped windows. There are two entrance doors.[3]
