The Pennsylvania Hospital was the most notable eighteenth century structure of its kind and its sterling architectural excellence becomes ever increasingly apparent with the flight of years. The only attempts at embellishment are upon the central pavilion and are both well-considered and restrained. All the rest of the building was carried out with the extreme simplicity of the eastern wing which was the first portion to be built and was erected in 1753. One could not find anywhere a more striking example of the transforming power of a string course of contrasting colour upon a severely plain wall. The white string course, standing out in strong relief against the deep red brick walls and passing between the row of window heads on the ground floor and the window cills of the storey above it, communicates to an extremely plain exterior a charm and dignity of aspect that redeem it from the bald austerity of a factory or barracks. Save this string course and the cupola atop the roof, this oldest portion of the hospital and the corresponding west wing are devoid of architectural adornment but their just proportions and easy amplitude of dimensions are particularly satisfying to the eye. Among the public buildings of the Colonial period, noteworthy both for their architectural character and for historic association, Carpenters’ Hall in Philadelphia, where the sessions of the first Continental Congress were held, demands the consideration of all patriotic Americans. Quite apart from its historic importance, Carpenters’ Hall challenges the admiration of every lover of Georgian architecture in its sturdiest manifestation. The State House in Annapolis, the Court House in Williamsburg, the Custom House in Charleston and other public edifices of similar character imparted to civic life in Colonial and post-Colonial days an element of dignity and poise.
