The Tappan-Viles House remains one of Augusta's most architecturally-impressive houses. Located just north of the Maine State House, the two-story house includes elements of its original Federal-style design as well as Italianate- and Colonial Revival-style elements that were added in c. 1865 and c. 1915, respectively. The house is named in part for Reverend Dr. Benjamin Tappan, who built it five years after becoming pastor of the South Parish Congregational Church, and for Blaine S.

The Ansel Blossom House is the oldest surviving building in Monmouth. It is an intact example of an early Federal-style cape form. It is a simple, one-story side-gabled building sheathed in clapboards with a center chimney. The windows are placed closed to the eaves and are made up of multiple small panes. They are asymmetrically arranged on the facade. The central entry door is unadorned, topped simply by a five-light transom. The house's south elevation is connected to a two-story structure added in 1894. Ansel Blossom was the son of Captain James Blossom.

Ezekiel Merrill built this large house just east of the Ellis River for his family of nine. Merrill and his family were a part of a group of Revolutionary War veterans from Massachusetts who chose to settle in the area due to its fertile intervale (a low-lying area near a river). After purchasing four lots in 1788, Merrill brought his family here in canoes. As the first European-American settlers to arrive, the area was essentially a frontier, and the family initially resided in a log house.

The Lincolnville Center Meeting House is located on Route 173 in the village of Linconlville Center. The two-story building features a gable-front roof and has a central entry. The building is largely unadorned, except at the front entry which is flanked by pilasters and topped with a projecting cornice. A molded fan is placed above the paneled wooden double doors. The interior is largely unchanged and contains wooden pew boxes and a balcony that wraps along three sides of the building. Interestingly, the meeting house's pulpit is located at the front of the building instead of the rear.

Richard Manning, a native of Salem, Massachusetts, moved to the Casco area to manage his family's large land holdings in the area after his father died in 1813. His sister, Elizabeth Clark Hawthorne, followed her brother to Maine along with her son and future author, Nathaniel Hawthorne. It is believed they spent some time at the house before moving into their own located a short distance away in Raymond. The Richard Manning House is a two-story wood frame dwelling, sheathed in clapboards with a shallow pitched hip roof, and two large interior chimneys.

Built by Joseph Woodman, a prominent local builder, for Dr. Royal Brewster, the house is a finely detailed Federal-style structure in a rural setting. It is a two-story, clapboard-sided house with a low-pitched hip roof and two end chimneys. The facade is symmetrical with a central entry. The door is flanked by sidelight windows and topped by a recessed arch. The entry is sheltered by a Greek Revival-style porch, a later addition. A simple band of wood separates the first and second floors. The denticulated cornice sits above a section of unusual zig-zag trim.

Sandwiched between Route 2 and the St. Lawrence and Atlantic Railroad tracks, the Peabody Tavern served as a stagecoach and later a railroad stop between Portland, Maine, and Lancaster, New Hampshire. It was built by Thomas Peabody, of Andover, Massachusetts, whose family was one of the first who settled the area. The tavern is a simple wood-frame, 2-story structure with an asymmetrically pitched side-gabled roof. A large ell extends off the rear on the east end of the main building. The facade is symmetrical with double-hung multi-paned windows.

Located just southeast of Windham Center, the Goold Family House is significant for its association with William Goold, a notable Maine author and historian. He was born at the farmstead in 1809 (though likely in a different house). He was a member of the Maine Historical Society and delivered fourteen papers before the society from 1873 to 1889. He also published a column in the Portland Press Herald and published a history of Portland, Portland in the Past. Goold served as a state senator from 1874-75. The house has undergone several additions since its construction.

Located northwest of Back Cove, the John B. Russwurm House is a two-story, wood-frame structure with a side-gable roof. Sheathed in clapboards, it features a symmetrical facade with a central entry door. The door is framed by a later Greek Revival-style surround of sidelight windows and pilasters supporting a wide entablature. The second floor windows sit just below the eaves. The two interior chimneys are located below the gable peak on the rear of the house. Russwurm was the son of a British Jamaican plantation owner and an enslaved women.

Containing one of Maine's earliest existing homes, the John Sedgley Homestead illustrates the evolution of a colonial era homestead. It is made-up of a variety of structures, including a c.1715 cape (pictured), farmhouse, carriage house, stable, and two additional outbuildings. John Sedgley was gifted the land by his father-in-law after marrying Elizabeth Adams. The cape was constructed as the couples first home. It is a low-posted, one-story dwelling with a side-gabled roof, sheathed in clapboards. The facade is asymmetrical with the entry just off center.
