Wall's design could be considered a late colonial survival or an early Colonial Revival, but either way it marks the continuing importance of the Revolutionary heritage in Lancaster. The pair of towers suggests the usual German two-towered facade, but the facade's details and both towers are diminutives of Abraham Colladay's steeple for the Lutheran congregation (
LA14). Baltimore architect Wall proposed the two-towered facade on the grounds that greater effect could be achieved for less cost than a single great tower. The interior is notable for its shallow plaster dome that spreads sound in the nearly square hall that is richly hued in the Victorian mode.
