Only 25 years later by the middle of the 19th century, the three retailers open new, larger stores to accommodate population increases in the city. Lord & Taylor and Arnold Constable both relocate along Broadway Street, north of Canal. Meanwhile, A.T. Stewart opens his “Iron Palace” department store at 280 Broadway, which was considered a marvel of architecture at the time. Soon however, new competitors start to enter the market, higher up Broadway near 14th Street. R.H. Macy opens his eponymous store on 14th St at 6th Avenue in 1858. This area further developed as new retail player B. Altman entered the fray and A. T. Stewart relocated for a third time.
