The Crown Jewel of Portland's Eastern Promenade! Built in 1898 for Henry F. Merrill—a prominent Portland industrialist—this grand home was designed by celebrated Maine architect John Calvin Stevens. In the same family since it was built, the new owner has meticulously renovated the Henry Merrill Mansion into three elegantly laid out full floor residences and stands as a testament to turn-of-the-century craftsmanship, reimagined. Commanding one of Portland's most prestigious addresses along the Eastern Promenade, the mansion offers sweeping views of Casco Bay and the working waterfront, while placing you steps from waterfront parks, trails, and the city's acclaimed dining and cultural scene. Original period details—soaring ceilings, rich hardwood paneling, stained glass, ornate mantels, and restored light fixtures—blend seamlessly with modern comforts, premium finishes, and updated systems throughout. Perched above the Eastern Promenade, the Penthouse has spectacular views and features. The nearly 2000 sq. ft. home features a private entrance, large bright airy rooms with vaulted ceilings, two bedrooms, two baths, laundry, den space, two private decks, and a spectacular round room dubbed 'the Observatory' by Stevens. Refinished original wood floors and an open, sunlit layout pair beautifully with a modern chef's kitchen and spa-inspired baths. Historic charm meets contemporary elegance in this exclusive top-floor private retreat. With dedicated parking, private outdoor spaces, and modern infrastructure throughout, the Henry Merrill Mansion offers a unique opportunity to own a piece of Portland's history—complete with the romance of Longfellow's circle, the vision of John Calvin Stevens, and the finest craftsmanship of both the 19th and 21st centuries. Three Residences. One Landmark Address. Endless Views.
