Built in 1715 in Karlsruche, Germany, this ancient castle sits at the center of the city with 32 streets radiating out from it, like spokes on a wheel, and was the seat of power for the Grand Dukes of Baden.
But just 150 miles from Karlsruhe Castle, a young boy was found claiming to have spent his life there, locked in a windowless cell. Just who was this boy, named Kaspar Hauser, and how was he connected to the Grand Dukes of Baden?
The Chateau de Moilans, in the South of France, seems to be impenetrable with its double moat, thick walls, and dungeon sitting at more than 75 feet high with 3 turrets.
In the 16th century, the chateau passed from its original owners, the Miolans family, to the powerful house of Savoy, who converted the fortress into a prison. And the jail's most famous inmate was a controversial literary giant.
It was in this prison that the notorious Marquis de Sade found himself after a party in 1772 that got a little too out of control ... and landed him an accusation of attempted murder.
In Manhattan sits a Palladian-style manor inspired by ancient Greek temples: the Morris-Jumel Mansion. Today, the mansion is preserved as a museum, but in its heyday, it served as George Washington's headquarters during the Revolutionary War.
Many of the home's original details remain, including 18th century stained glass, an octagonal sitting room, and a bed said to have been a gift from Napoleon. And when a séance is held inside the mansion, the owner appears from the beyond.
This 24-room, Spanish-style villa in Centerport, NY, was designed by the same architectural firm that built Manhattan's Grand Central Terminal. And it was once home to one of the most famous and powerful families in American history, the Vanderbilts.
The Vanderbilt Museum, which sits on the family’s 43-acre estate named the Eagle’s Nest, houses William K. Vanderbilt II’s marine, natural history and ethnographic collections. Visit the museum for a “living tour” where guides bring the home to life with a performance taking visitors back in time.
Dating back to the 16th century, this 300-acre sprawling estate in the rolling hills of Nottinghamshire in central England is the red-brick English manor house known as Thrumpton Hall.
Inside, the home boasts a magnificent library, and the windows display the coats of arms of the families who once inhabited these halls. But over 4 centuries ago, Thrumpton's occupants became entwined in a secret plot to strike a fatal blow to the English monarchy.
Standing proudly on the north bank of the River Thames is an iconic fortress -- the Tower of London. Built in 1066 as a royal residence, it's where the crown jewels are held securely for the monarch.
