What do Queen Elizabeth I, the Vanderbilts and the founder of athletic brand Under Armour have in common? A sprawling equestrian estate in Maryland that just hit the market.

The more than 400-acre property in Reisterstown – a rural area outside of Baltimore – is known as Sagamore Farm. It listed privately for $22 million earlier this week, according to a press release from listing agent Denie Dulin of Compass Baltimore.

Currently, the farm is owned by Kevin Planck, the founder and CEO of Baltimore-based Under Armour. Planck bought the property in 2007, and used it as a guest house, retreat center for employees and horse-training facility, he told the Wall Street Journal.

“Restoring Sagamore Farm to its former glory has been one of the greatest joys in my life,” Planck said in a statement. “But now it’s time for the next steward to carry the torch and continue its legacy for generations to come."

In all, the estate has three houses. The largest of those is a 16,000-square-foot main house known as the “Top of the Valley” given its panoramic views of the nearby Worthington Valley. The house has seven bedrooms, ten bathrooms, a conference room and a gym.

It’s designed for “both elegant entertaining and luxurious everyday living,” Dulin wrote in a description of the listing.

There’s also a five-bedroom, four-bathroom house with a pool where the general manager of the property lives. The third residence, built in 2014, is known as the “Bunkhouse” and it includes eight apartments for staff and jockeys staying on the farm.

Equestrian heritage

More than its size, the property boasts a storied history in equestrianism.

In 1925, the estate was established by Isaac Edmondson, a businessman known for creating the medicine Bromo-Seltzer. Eventually, it was passed on to a member of the Vanderbilt family who transformed the estate into a world-renowned equestrian training and breeding facility.

At one point, Queen Elizabeth I kept a female breeding horse at the farm. Over the years, several championship horses have been trained at the facility.

"Sagamore Farm isn’t just an iconic Maryland farm; it’s a living testament to American greatness,” Planck said. “The moment you walk through those gates, you can feel the significance of its history and the spirit of champions.

Now, Dulin is touting the property’s accessibility to major east coast cities as well as its potential for an equestrian insider. In addition to the residences on the grounds, there are also three barns, a racetrack and facilities for training and breeding horses.

“Whether seeking a legacy property for breeding and training or a visionary expansion into new disciplines, Sagamore Farm is a rare offering of exceptional grandeur, equestrian heritage and truly
limitless potential,” she said in the listing description.
