Whether you are a resident or just coming into town to see the sites, everyone should visit this incredible place. Known as “the finest private house ever built in America,” the grounds and façade are once of a kind, dating back to the early 20th century. Plan to spend a good hour or two visiting the Renaissance-inspired gardens—with Mediterranean-style landscaping in a subtropical climate—and adjoining museum, which showcases 34 decorated rooms filled with art and European treasures.
