Hartland’s Castle, an iconic mansion by the sea in Old Saybrook, CT, is on the market for $7,749,000. It comes with a fascinating history.

The 11-bedroom chateau with 15,000 square feet of living space was built in 1908 for an American heiress and her husband.

“It was built for George Watson Beach and his wife, Elizabeth Colt Jarvis Beach, with aspirations to be the equal of the Newport summer cottages,” says listing agent Chuck Haller. “The 40-room home was designed by Alfredo S.G. Taylor in English Tudor Revival style.”

Elizabeth, the niece of gun manufacturer Samuel Colt, and her husband already owned hundreds of acres in the area, as well as a home in Hartford. Their beach house was completed in just two years and was said to include a clock tower that chimed every half-hour to the tune of “Don’t Say Goodbye, Say Au Revoir.”

In 1923, Otto Lindbergh, uncle of aviator Charles Lindbergh, purchased the castle for $75,000 and turned it into a hotel for the rich and famous. Guests included big names like Howard Hughes, Helen Hayes, Clark Gable, Charlie Chaplin, Frank Sinatra, and Doris Day, among others.

Over the years, the property changed hands several times. The current owner, Maria Rand, picked it up in 2007 for just over $2 million.

The property was renovated and turned back into a private residence. Original details include 11 fireplaces; a three-story, hand-carved cherry staircase; and a gentleman’s smoking room.

“The home includes a turret with a sitting area on top, a media room, an infinity-edge pool, and an elevator,” Haller says. “A two-car garage with a one-bedroom apartment was also added.”

The town is a popular summer destination, Haller says. “Old Saybrook is a seashore town. There are beaches, parks, and marinas, and the main street offers unique shopping and dining opportunities.”
