The St. Nicholas Hotel was a 600-room, mid-nineteenth century luxury hotel on Broadway in the neighborhood of SoHo in Manhattan, New York City. It opened on January 6, 1853, and by the end of the year had expanded to 1,000 rooms. The St. Nicholas raised the bar for a new standard of lavish appointments for a luxury hotel. It was the first New York City building to cost over US$1 million. The hotel was said to have ended the Astor House's preeminence in New York hostelry.
