Morgan & Co. and designed by Trowbridge and Livingston.","why_significant":"It was the long-time headquarters of the J.P. Morgan banking firm, whose address became known worldwide as \"the corner.\" Its design reflects Italian Renaissance and neo-classic influence and fits an irregular corner lot. The main banking room used overhead trusses to avoid interior supports, and the exterior has barely changed since construction.","narrative":"Standing at the angle of Wall and Broad Streets in Manhattan, 23 Wall Street served as the headquarters of the J.P. Morgan banking interests, and its address became known in financial circles simply as \"the corner.\" Trowbridge and Livingston designed the four-story building, begun in 1913 and finished in 1914, shortly after J.P. Morgan's death. Morgan had chosen the pink Tennessee marble exterior and wanted a main banking room without visible interior supports, which led to a system of overhead trusses carried on steel built up through the walls. The odd-shaped lot and diagonal corner entrance determined the plan, and Italian Renaissance details, including a carved cornice, mark the facades. The entrance carries no nameplate, only small gold numerals. After a 1959 merger with Guaranty Trust Company, the interior was remodeled in 1961-1964 and linked to 15 Broad Street, while the exterior stayed virtually unchanged, even keeping scars from the 1920 Wall Street explosion.","period_of_significance":"1913-1914","architect_builder":"Trowbridge and Livingston","architectural_style":"Neo-classic with Italian Renaissance influence","criteria":[],"status_note":"Listed as occupied and in excellent condition; unaltered on its original site apart from blocked basement windows and entry and a 1955 penthouse.
