|Gallery: Millionaire's Row
||2 of 5
When Henry Clay Frick built his imperial mansion at 70th Street, he told friends he was doing it to "make Carnegie's place look like a miner's shack." For Frick, it was not a new idea. In Pittsburgh, his 20-story office building was designed to blot out the sun of Carnegie's smaller building next door.
Frick's marble palace housed one of New York's finest collections of art, which had been moved from Pittsburgh where it was threatened by the smoky air. Along with Carnegie's, Frick's mansion is one of the few remaining along Millionaire's Row.
