Sagamore Farm, a storied equestrian estate in Maryland, is up for sale for $16.5 million. The property, which dates back to 1925, is interwoven with some of the world's most impressive dynasties, including the Vanderbilts and the British royal family. Despite its impressive heritage, it has not been able to find a buyer due to its lack of concrete offers. Set on approximately 440 acres in Glyndon’s Worthington Valley, the property offers a world-class equervership with a grand home rooted in a century of history. The main residence, which includes seven en-suite bedrooms, nine full bathrooms, and one half bath, is over 16,000 square feet. Additionally, the farm's infrastructure reflects its heritage as a premier thoroughbred facility.
