The Chapel, often referred to as a miniature Gothic gem, is an excellent example of Gothic Revival architecture and the only known example of Renwick's Gothic Revival church design in DC.
The Chapel is constructed of Potomac gneiss with an east-west gable roof is of grey slate. The west facade contains the main entrance with a large two leaf pointed, brown door with 4 lancet panels in each leaf. The walls are paneled with a dark wood wainscoting. The double lancet windows have a brown, painted, heavy wood frame and mullions. The finely proportioned chapel, skillful use of material in the contrast of sandstone and gneiss as well as attention to detail reflects the sensitivity of the architect, Renwick.
James Renwick also designed Grace Church and St. Patrick's Cathedral in New York City. He was appointed architect of the Smithsonian Institution in 1846 and the resulting building was one of the most important examples of American Gothic Revival.
Both the site and the architecture of the Oak Hill Chapel have remained virtually unchanged in the years since the Chapel was built.
