A student of Richard Morris Hunt, the architect George Browne Post was a bit of a starchitect in his own right during the latter half of the 19th century. The Civil War veteran -- and former civil engineer -- was responsible for many precursors to the modern skyscraper. He designed NYC's eight-story Equitable Life Assurance Building, the first building to feature passenger elevators, as well as the New York World Building, a 20-story newspaper headquarters commissioned by Joseph Pulitzer that was, at the time, the tallest building in the city. Therefore, it's not exactly shocking that his country residence in northern New Jersey is an architectural gem in its own right. The striking Neo-Georgian mansion is one of 30 country houses that Post and his firm constructed in Somerset County, and seems to be one of the better preserved. The seven-bedroom, seven-bath columned manse sits on 70 bucolic acres and is currently asking $10.8 million.
