Arnold Constable & Company was a department store chain in the New York City metropolitan area.

At the company's peak, its flagship "Palace of Trade" in Manhattan – located at 881-887 Broadway at East 19th Street, through to 115 Fifth Avenue – was acknowledged to be the store which took the largest portion of the "carriage trade", in New York, serving the rich and elite of the city, such as the wives of Grover Cleveland, Andrew Carnegie, Thomas Edison, J.P. Morgan, John D. Rockefeller and Cornelius Vanderbilt.

[1] In 1857 the store moved into a four-story white marble dry goods palace located at 309-311 Canal[2] with frontages on Howard and Mercer Streets.

[1] A few years later as the country suffered from inflation, the store became one of the first to issue charge bills of credit to its customers each month instead of on a bi-annual basis.

[3] At the time, Arnold Constable was the second largest dry goods store in the city,[1] and the building was called the "Palace of Trade" by newspapers.

[1] Among the properties the company owned was an office building at Fifth Avenue and East 18th Street, which connected to the firm's gigantic emporium.

Later suburban expansions included locations in Hempstead and Manhasset on Long Island, Upper Darby Township, Pennsylvania and in New Jersey.

[10][11] The second Arnold Constable flagship store now located in the Ladies' Mile Historic District began as the second of two twin buildings with marble facades, both designed by architect Griffith Thomas in Second Empire Commercial style,[12] the other being for the retailer Edward Hoyt, who moved uptown to the area at about the same time as Arnold Constable.

[13] The Arnold Constable building grew by accretion over time, with sections divided by brick firewalls, but the interiors were kept as open as possible, supported by only cast-iron columns to allow for flexibility in displaying merchandise.

In 1883-84, an annex was added on 18th Street, which was connected to the main building by a four-story bridge, and directly at the ground floor and basement.
