History buffs, consider a move—or at least a field trip—to Chappaqua, N.Y., the site of Horace Greeley's former barn, converted in 1890 by his daughter to a sprawling family home and listed for $1.299M. Constructed for the New York Tribune founder in 1856, the home is billed by the brokerbabble as the first stone-and-concrete structure to be built in the United States. The purportedly thrifty Mr. Greeley is said to have chosen to build with stone in large part because it was a more economical option over the traditional wooden barns of the day. More staying power, too, we might add. Today, the grand home looks to have aged remarkably well. Offering five bedrooms, crazy-high ceilings, the somewhat vague promise of "many fireplaces and stoves throughout," and a professional home office (currently serving as a doctor's consultation office) this Westchester County home looks to be classic American gem.
