'If once you have slept on an island, you'll never be quite the same,' wrote poet Rachel Field. Take the year-round mail boat from Northeast Harbor and discover why. The house was built in c.1872 for Colonel William Hadlock, who was twice elected to the Maine Legislature and served in the Civil War with the 28th Maine Infantry Regiment. Its yellow exterior and commanding presence make it a landmark on Main Street. Ideally located near the harbor, the property offers easy access to the year-round mail boat--or your own vessel--and to all the pleasures of island living. The main house features eight bedrooms and 2.5 bathrooms across three floors. Enter through the covered side porch into a mudroom that leads to an eat-in kitchen with wood floors and cabinetry. High ceilings enhance the sense of space. The adjacent dining room features crown molding and wide wood floors, and a half bath completes this level. A comfortable den with half wainscoting offers additional living space. The living room provides partial harbor views, a front-loading wood stove, and double front doors with a vestibule. The second floor includes an attractive landing, a full bathroom with tub and shower, and four bedrooms--one of which opens to a private porch with harbor views, ideal for morning coffee while watching boats come and go. The third floor offers four additional bedrooms and another bathroom. A full basement and a six-room addition--historically used for laundry, workshop, and storage--present significant potential for reimagining by a new owner. Over more than 50 years of ownership, the Colonel's has been thoughtfully restored, preserving its historic integrity while incorporating the comforts expected for modern, year-round living. This move-in-ready island home offers timeless character and is ready to welcome its next steward to enjoy--and share--the enduring charm of this remarkable setting.
