A.T. Stewart Mansion, ca. 1870s.

Alexander Turney Stewart was an Irish-born businessman, who, by 1850, owned the largest emporium in the world and was among the richest men in New York. And rich men in New York built themselves fancy houses. The A.T. Stewart Mansion, a white marble French Second Empire mansion was completed around 1870. (While most mansions were built with brownstone at this point, his white house stood out.) As ornate as the exterior was, the interior was equally so, described by a historian as, "an explosion of bric-a-brac, statuary, furniture, and art." Stewart died only six years after the home was finished, and his wife was subject to a prorogued legal battle over his fortune (this included the theft of his body for ransom)! After a decade of diminished mental health, that had her wandering the halls of the home talking to nonexistent people, Cornelia Mitchell Stewart died in 1886. The manse would only survive 15 more years before being razed in 1901, just 30 years after completion.
