Though this late 19th-century Vanderbilt family mansion stands in a part of Rhode Island that is chock full of grand mansions, The Breakersstill soars above the rest. Designed by famed architect Richard Morris Hunt, the125,339 sq ft, 70-room Italian Renaissance-style palazzo was inspired by the 16th-century palaces of Genoa and Turi.

This stone castle was built by one very remarkable man, Harry Delos Andrews. Andrews served as a medic during World War I where he became sick with meningitis and was declared dead prematurely. By the time word got back to America, six months later, that he was alive, his fiancée had already married someone else. Andrew took off on a grand tour of Europe and explored many castles. He eventually became a boy scout troop leader of a squad called the Knights of the Golden Trail, and frequently camped at a secluded part of the Little Miami River in Ohio. Andrews built stone tents to keep their camping gear and supplies by the creek safe and dry. The structures became a full-blown medieval castle—Loveland Castle. Now, troops can still spend the night on the premises while visitors can tour the property while admiring a collection of swords and other old weapons.

Easily the country’s most famous castle, this National Landmark took decades to be built by newspaper magnate William Randolph Hearst and architect Julia Morga.

Situated almost exactly halfway between San Francisco and Los Angeles on the scenic Pacific coast, Hearst Castle is a popular stop for roadtrippers.

Boldt Castleand its nearby yacht house have since been completed and can be visited during the warm months.

Upon his death, the state of Connecticut took over the property in 1943 and turned it into a state park.
