By the mid-19th century, the early Federal- and Greek Revival-style homes were replaced by more-solid structures of masonry and cast iron, and along Broadway, large marble-skinned commercial establishments began to open, such as Lord & Taylor, Arnold Constable & Company and Tiffany & Company, as well as grand hotels such as the St. Nicholas and the Metropolitan. Theatres followed in their wake, and Broadway between Canal and Houston Streets became a lively theater and shopping district and the entertainment center of New York; as usual with such areas, it was home to many brothels as well, and the side streets off of Broadway became the city's red-light district. As this change in character drove out the middle-class, their place was taken by small manufacturing concerns, including cabinet-makers and the lumberyards that supplied them, brass and copper firms, makers of china and glassware, locksmiths, snuff manufacturers and book publishers.
