Are there any interesting historical landmarks or sites near Hyde Park?

Oh my gosh, Hyde Park has some ultra famous ones! Namely the Franklin D. Roosevelt Historic Site with the presidential library and museum, "Top Cottage," the presidents retreat and Val-Kill, the first lady's retreat. They have exhibitions of his presidential days and you can see both his desk which remains untouched from his last day in office to his beloved car. You can also go to the stunning and lavish Vanderbilt Mansion Historic State to tour the homestead and the gorgeous grounds.
