The Classical Revival can be differentiated from its Georgian and Federal cousins in that the execution is typically more academically rigid, or formal, in execution. Based in classical Roman precedents, It is also typified by a two-story front porch supported by classical columns and either pedimented or crowned with a balustrade, or railing. The formal entry door is typically crowned by an elaborate pediment, often with a high-style, curvilinear broken pediment, sometimes referred to as a “swan’s neck”.
