There is a particular quality to the finest American properties in which a sense of scale meets story that goes beyond architecture. It is a country where French Beaux-Arts craftsmanship lines the streets of Philadelphia, where Italian wine varietals grow along the Napa River, and the dream of the “last frontier” in a 52-acre Aspen compound. On the 250th anniversary of the Declaration of Independence, here are ten properties from our Concierge Auctions portfolio that capture exactly that.
