23 Wall Street or "The Corner", is an office building formerly owned by J.P. Morgan & Co. - later the Morgan Guaranty Trust Company -located at the southeast corner of Wall Street and Broad Street, in the heart of the Financial District in Manhattan, New York City. The building was designated a New York City landmark in 1965, and was added to the National Register of Historic Places in 1972.
Designed by Trowbridge & Livingston and built in 1913, the building was so well known as the headquarters of J.P. Morgan & Co. - the "House of Morgan" - that it was deemed unnecessary to mark the exterior with the Morgan name. The building is known for its classical architecture and formerly for its well-appointed interior, including a massive crystal chandelier and English oak paneling, but, overall, is more notable for its history than its architecture.
Even though property prices in the area were very high, the Morgan building was purposely designed to be only four stories tall; the contrast to the surrounding high-rises is reinforced by the astylar exterior, rendered as a single high piano nobile over a low basement, with a mezzanine above, and an attic storey above the main cornice. The plain limestone walls are pierced by unadorned windows in deep reveals. The foundations were constructed deep and strong enough in order to support a forty-story tower should the need arise in the future.
In 1957 the building was linked to neighboring 15 Broad Street, a 42-story L-shaped tower on a limestone base that tactfully echoes 23 Wall Street's facade. In 1989, JP Morgan moved its operations to 60 Wall Street, a larger and more modern building two blocks to the east. 23 Wall Street was extensively renovated in the 1990s as a training and conference facility for J.P. Morgan & Co., destroying the grand banking hall.
This building and 15 Broad Street were sold in 2003 for $100 million to Africa Israel & Boymelgreen. The two buildings have become a condominium development, Downtown by Philippe Starck, named for French designer Philippe Starck, one of a growing number of residential buildings in the Financial District. Starck made the roof of 23 Wall into a garden and pool, accessible to the residents of the development. Africa Israel gained full control of 23 Wall Street in 2007; it was sold to a partnership of the China International Fund and Sonangol Group in 2008.
