The Church of St. Martini et Nicolai, dating back to the 14th century, is located in Steinkirchen, part of the Erste Meile in the Altes Land region.

In 1687, the organ builder Arp Schnitger constructed an organ for the church, incorporating some pipes that dated from the 16th century. Over the centuries, the instrument remained largely unchanged and was restored in 1947–1948, 1987–1991, and again in 2012.
