The simple, tall gable-fronted chapel is built of rock-faced limestone in regular courses. Window and door openings are round-arched. A short square, three-stage corner tower contains the entrance. Its first stage is built of limestone, and the second (louvered) and third (round-arched) are wood-framed with horizontal wood siding. Corner boards are treated as pilasters, with simple capitals. The most distinctive feature of the church is the tower’s roof, a tall polygonal spire with flared bracketed eaves.
Across the street at 401 S. Chestnut Street, the First Presbyterian Church (1960), has a long gabled nave of limestone, a front portico supported by four Tuscan columns, and a wooden three-stage polygonal tower over the west end punctuated with a needle spire.
