Brown Marsh Presbyterian Church was organized prior to 1756 by the early Scots who settled in the area. The first two buildings were made of logs. Until 1848 the church was also used for secular education.

The present structure was built in 1818. It is a substantial frame house with hand-dressed cypress weather-boarding. The church is constructed entirely with handmade iron nails. The building is supported by pillars made from heart pine believed to have been erected in 1818. There are 18 small panes in each window. The wooden shutters are attached by handmade hinges in the shape of the carpenter's square. The pews, pulpit, wooden window closings, rough cedar siding and cedar shingle roof are original.

There is a cemetery. Services are not held here and it is rarely open to the public.

It is located 2 miles north of Clarkton on Brown Marsh Road.
