If you're in the market for a new home and have $2 million to spend, this may be the place for you. It belonged to the late American sculptor Alexander Calder, inventor of the kinetic mobile structure. Built in 1917, the home is situated on 2.6 acres of land (originally 11 acres), located in the Croton-on-Hudson region of New York's Hudson River Valley. There are views of the river and huge rock walls that surround the 5,400 square foot, five-bedroom home and three bathroom home, for ultimate privacy and relaxation. Just remember to invite us up every now and then as a thank-you for putting you on.
