The Greek Revival church was built in 1833 as a meeting house style building, with the steeple being added in 1899. Possibly since the time the Wilmington Baptist Church was first submitted by Marine Biologist in 2010, the NRHP Nomination Form had been digitized and is now available. The pertinent section from the from follows.
The buildings and structures included in the Wilmington Historic District are as
follows (numbers refer to the enclosed sketchmap):
33. Wilmington Baptist Church, 1833, Greek Revival: Originally organized in 1806, the Baptists of Wilmington erected this frame church in 1833. The temple-front has a two-story, three-bay portico supported by tapered Doric columns. Doric pilasters are placed behind the columns at the corners and an entablature with molded cornice surrounds the building. The central entrance has double doors and a panelled surround. Within this surround are two crosses, also applied, each flanking the doorway. The three large windows on left and right elevations and the two on front elevation have stained glass.
A steeple, built in 1899 surmounts the building and has three stages: the clapboard base supports the belfry which has wooden fan-shaped spandrels in each corner, forming somewhat triangular openings. Above is another stage with circular blinds on each side. A steep, slate-covered roof surmounts the steeple within, in turn, is capped by a weathervane. The church has clapboard siding and a slate roof. A centrally located exterior brick chimney is at the rear. A one-story lean-to with scroll brackets on posts protects a side entrance on the left elevation.
