The medieval-style castle was originally built for fourth-generation winemaker Dario Sattui and is now one of the most popular wineries in the area.

Pirro moves on to explore the Olana State Historic Site in Hudson, New York — an ornate villa designed by painter Frederic Church.

The 250-acre property, known as Church’s living masterpiece, is now a National Historic Landmark for visitors to enjoy daily.

Keeping to the Empire State, Pirro travels to the campus of Manhattanville College in Purchase, New York, to check out Reid Castle.

The renaissance revival structure was completed in 1892 as a private home for Whitelaw Read, a diplomat and owner of The New York Herald Tribune.

Pirro’s last stop is at the stone walls of Cairnwood Estate in Bryn Athyn, Pennsylvania.
