The current church has a single-story rectangular stuccoed brick main block, three bays by three, resting on a partially excavated fieldstone foundation and covered by a steeply pitched slate roof. It features a 4-story bell tower with broach spire and patterned slate roof. This Gothic Revival structure was built in 1870–1874 but incorporated the walls of the earlier churches of 1824 and 1735. A graveyard surrounds the structure. The structure was designed by Thomas Dixon, a Baltimore architect.
