Battery Steele, located on the former Peaks Island Military Reservation on Peaks Island, in Portland, Maine represents the most advanced form of Coastal Defense installation developed by the United States Army during World War II. Due to its location as an outer island in the bay with a clear view across the North Atlantic, Peaks Island was chosen as the principal site for Casco Bay?s defensive system. The battery was armed with two 16? guns capable of firing a 2000 pound shot 26 miles to sea.

Parson's Bend is a very good, intact example of the simple, transitional Georgian - Federal period homesteads that were prevalent at the turn of the nineteenth century in mid-coast Maine. Situated on a low bluff over the Sheepscot River, one-and-one-half miles southeast of the Puddle Dock settlement in Alna, the home that Jacob Nelson built has changed very little since its was constructed circa 1800.

The Lt. Robert Andrews house is a center-chimney Federal style home, sandwiched within a century of additions, in South Bridgton, Maine. Built by one of the most influential and benevolent men to live in the town during the late-eighteenth and early nineteenth century, Andrews is remembered for his lifelong dedication to military, philanthropic and civic service in his community. Twenty five years after settling in town, Andrews built a large home on his land across from Adams Pond.

The Timothy and Jane Williams House is among the finest mid-nineteenth century homes in Rockland Maine, and quite possibly the most significant Italianate style structure in this seaside city. The house, which has been attributed to the local joiner and builder James Overlock, was erected circa 1859, and features high style decorative exterior elements including quoins, brackets, flush board siding, an elaborate entryway and decorative crowns over the large windows.

The Joseph H. Underwood House in the Fayette Mills section of Fayette, Maine is a building that reflects the achievements and status of one of this town?s most successful merchants, farmers and politicians. Constructed in 1837, the large brick house and integral ell was Underwood?s third residence in the town to which he had moved thirty years earlier. During these three decades, Underwood had established a successful store, invested in numerous local industries, and served as an elected official in a variety of local and state offices.

As Maine communities began to lose some of their frontier aspects in the early nineteenth- century and assumed a more settled appearance, rudimentary civic improvements were initiated. Among these improvements in the largely agricultural world of rural Maine was the regulation of the livestock which were becoming numerous. To address this problem towns constructed shelters for the temporary control of wayward animals. The existence of 21 of these structures in Maine have been verified, and their condition varies from almost unrecognizable to good.

The Haystack Mountain School of Crafts in Deer Isle Maine is an integrated complex of wooden buildings designed by New York architect Edward Larrabee Barnes starting in 1959. The complex, which contains craft studios, bunkhouses, administration buildings, and a dining facility, is simultaneously cleaved to and floats above a steep hillside overlooking Jericho Bay and the Deer Isle Thorofare.

The John B. Colcord Farmstead is an agricultural complex comprised of fields and woods, a house, barn, and multi-function outbuildings in Benton, Maine. The extant structures generally represent domestic and agricultural activities from the 1880s, 1899, and the 1930s through the 1980s, while the history of the land stretches into the 18th century.

In 1980 the Leonard Bond Chapman House in Portland Maine was placed in the National Register for its architectural significance, and for its association with Chapman, a nurseryman, newspaper editor and historian who concentrated on the history of Portland and the surrounding area. The house that he erected between 1866 and 1868 is a well-designed and well-preserved example of an Italianate structure with a distinctive porch, tower, and mansard roof.

The former Abyssinian Meeting House is historically significant as the religious, educational, and cultural center for Portland?s nineteenth-century African American population. It is the earliest religious property associated with a black congregation in Maine (1828). The property also hosted a school for African American children, a residence for the minister, and may have been the site of a community spring or well. Prior to and during the Civil War members of the Abyssinian congregation were associated with abolitionist activities in Portland.
