Located at historic Diamond Cove, Maine's premier island resort, resides the former Post Headquarters. This impressive historic beauty is a rare stand-alone home that majestically sits at the head of the parade grounds. This 5 bedroom home was recently remodeled while thoughtfully keeping the historic charm and period details; including original tin ceilings, grand staircase, soaring ceilings, and custom built-ins. Enjoy a first floor bedroom, newly remodeled bathrooms, custom kitchen cabinets, two sinks/two dishwashers, and historic bowling alley countertops original to the island, custom bookcases, refinished hardwood floors, and a new full bath added on the third floor. Hand painted murals add a nautical whimsy and casual charm. Views of the parade ground from the large, covered front porch. Centrally located to access all island amenities including pool, tennis, gym, beaches, and more. Strong rental history. This peaceful and relaxing island retreat is less than two miles by boat from Portland, Maine's largest city.
