Blenheim Mansion

In 1875, canning magnate Henry Amos Osborn and his wife Frances purchased 220 acres of the Blenheim estate, just west of Havre de Grace. Seeking to create a grand country residence, Osborn commissioned Bel Air’s Jacob E. Bull - Harford County’s master builder - to design and construct a stately Victorian mansion. The result was a 17-room architectural masterpiece, perched on two manmade terraces and adorned with intricate woodwork, stained glass transoms, eight ornate fireplace mantles, and heart pine floors.
​
Jacob Bull’s craftsmanship and Osborn’s vision produced what the Maryland Historical Trust later described as “one of the finest surviving examples of the villas built by Harford County’s wealthy industrialists at the end of the nineteenth century.” Remarkably preserved, Blenheim remained in the Osborn family until 1925. It later served as a filming location for Disney’s Tuck Everlasting in 2002. Today, the mansion stands as a testament to the opulence and ambition of Maryland’s Gilded Age elite.
