Within the building there is much splendid interior wood finish. Its best feature, however, is the high, broad hall, with fluted Ionic columns supporting a mutulary Doric entablature, leading back to a double winding staircase, which is a marvelous work of art, combining the simplicity and purity as well as the beauty of the middle Georgian period. There are two landings on each flight, and from the spiral newels at the bottom the balustrades with ramped rails and heavy, turned balusters swing upward, as do the staircases, to the third floor. One notes with interest the unusual outline of the brackets under the overhang of the stair treads. A few important public buildings of Philadelphia that were not erected until early in the nineteenth century had their inception directly or indirectly in the outgrowth of the War of Independence, and their omission would render any treatise of the public buildings of the city noticeably incomplete. Their inclusion here finds still further justification in the fact that they are of classic architecture and so to a degree in accord with Colonial traditions. The Custom House, a classic stone structure, on the south side of Chestnut Street between Fourth and Fifth streets, was built for the second United States Bank, authorized by Congress in April, 1816, because of the bad financial condition into which the government had fallen during the War of 1812. The building was designed by William Strickland, in his day the leading American architect, being modeled after the Parthenon of Athens. It was completed in 1824 and was put to its present use in 1845. The main building of Girard College on Girard Avenue between North 19th and North 25th streets, of which Thomas Ustick Walter, a pupil of Strickland's, was the architect, is one of the finest specimens of pure Greek architecture in America. Indeed, this imposing Corinthian structure of stone has been called "the most perfect Greek temple in existence." Work upon it was begun in 1833, and the college was opened January 1, 1848. To a sarcophagus in this main building were removed the remains of Stephen Girard in 1851. The building is 111 feet wide and 169 feet long, and is surrounded by thirty-four fluted columns fifty-six feet high and seven feet in diameter at the base, which cost thirteen thousand dollars each. The total height of the building is ninety-seven feet, and it is arched throughout with brick and stone, and roofed with marble tiles. The weight of the roof is estimated at nearly one thousand tons.
