Philadelphia architect Walter designed this church to replace the congregation's church that had burned. His drawings were turned over to Cosby, who had done the brickwork for Thomas Jefferson at the University of Virginia and had built several of Virginia's temple-form courthouses. Cosby may have been responsible for some aspects of the interior design. The church is stuccoed to resemble stone and is set on granite foundations. Originally, a square belfry with a tapered spire that was later removed rose above the six-columned pedimented Greek Doric portico. The church has one of Petersburg's most spectacular interior spaces. An entrance lobby leads to an auditorium-like space with a balcony on three sides that is supported on cast-iron columns and a rounded apse with a modified Corinthian colonnade.
