This 23-room mansion, once the Livingston family estate, sits on 434 acres along the Hudson River north of Rhinebeck. Built in the Federal style, the mansion was remodeled in the mid-19th century by noted American architect Andrew Jackson Davis, who applied a classical revival style. The well-maintained house is closed for restoration, but the grounds alone are worth seeing; they encompass orchards, flower gardens, and ancient trees, and offer plenty of picnic-perfect spots.
