Merchants' Exchange Building

Address: 143 S 3rd St, Philadelphia, PA 19106

Neighborhood: Independence Mall


Description: Built between 1832 and 1834, the Merchants' Exchange Building, also known as the Philadelphia Exchange, is located on the triangular site bounded by Dock Street, Third Street, and Walnut Streets. This monumental office building was designed by William Strickland and is an exquisite expression of the Greek Revival style, the first national American architectural style. Formerly a commercial and financial hub in the heart of the city, the building eventually housed a post office--the first in the country to sell stamps--and is now home to offices of Independence National HistoricalPark.
