Some of the country's most beautiful historic homes are just a couple of hours outside of New York City - take a peek inside 4 of them

New York's Hudson Valley is filled with iconic sites that some of America's most influential figures once called home. Politicians, artists, businessmen, and socialites built beautiful estates here in the 1800s, and many are still standing today.

As he grew up in a historic estate named "Aberdeen on the Hudson", which was built in 1802, architecture photographer Nathaniel Cooper grew an appreciation for sturdy, 19th-century design.

"As an architecture photographer, I'm primarily hired to photograph new constructions with modern furnishings," Cooper said to Business Insider. "Photographing historic homes with original and/or era-themed furnishings allows me to catch a glimpse of culturally unique and completely different time periods."

Combining his two interests of architecture photography and historic homes, Cooper got exclusive tours inside some of the most historic homes in the Hudson Valley. Below, see the interiors of homes that once housed Franklin D. Roosevelt and the Vanderbilts.
