GIRARD NATIONAL BANK, 116 South Third Street; portico of the Third Street front is Corinthian, studied from the Parthenon and Temple of Saturnus; it stands on a stylobate, elevated above the pavement by steps on three sides, which gives it emphasis and dignity, and marks it as the feature of approach to the building; this portico is flanked on either side by a pavilion of pilasters, of the same character as the columns of the portico, the space between the pilasters being pierced with windows which are adorned with architraves and cornices supported by carved brackets; the pilasters and columns are surmounted by a cornice pediment and balustrade of great elegance of detail and proportion, studied from the best class of Roman antique work; the tympanum of the pediment is enriched by the date of the erection, 1795, and the American eagle in bas-relief carving, of excellent modeling; from the pavement to the apex of the portico is fifty-six feet; entire front is of Pennsylvania blue marble; the building was erected for the Bank of the United States in 1797, and followed closely the lines of the Dublin Exchange; architect, Samuel Blodgett; marble work was done by Claudius LeGrand in his yard at Tenth and Market Streets; this was the first building in Philadelphia to be erected with portico and pillars; in 1901, it was carefully renovated by James H.
