Once a booming mill village, the Head Tide Historic District is now best represented by fourteen eighteenth-century and nineteenth-century houses. Of these fourteen, six were present at statehood, including the pictured Plummer House. Named after the furthest point upstream where a river is affected by tides, the district is situated on either side of the Sheepscot River and surrounded by hills.

Comprising much of Main Street, Whitman Street, Deering Street, and Danforth Street, the Norway Historic District includes the historic commercial and residential center of Norway. Main Street includes numerous commercial, industrial, and civic buildings constructed of brick or wood, while the intersecting cross streets boast mostly wood frame residential buildings. One of the oldest commercial buildings, the Leavitt Hardware Building (pictured center below) was constructed in 1816 with additions made in 1851. It is a modest two-story wood frame structure with a gable front roof.

Composed of five historic properties and situated on thirty acres of land, the Sedgwick Historic District is located on Route 172 at Old County Road north of Sedgwick proper and contains some of the earliest buildings constructed in Sedgwick. The Town House (pictured) was originally constructed as the Congregational Church in 1793. In 1849 religious services were discontinued at the building and the town voted to make the former meetinghouse the Town House. As a result, the town lowered the roof by ten feet and removed interior seating galleries.

Located on Burgess Road and one of the earliest houses constructed in this remote part of Maine, the Burgess House has had several additions constructed throughout the nineteenth century with all the components sheathed with clapboard siding with side-gabled roofs. The original structure is a one-story Cape with double-hung windows with numerous small panes of glass. Characteristics of a Cape are its low, broad massing with interior rooms placed around the large central chimney. The entrance is framed by five-paned sidelights and a louvered transom.

While it may no longer serve as an educational facility, the Red Brick School in Wiscasset remains a significant example of Maine's pre-statehood ties to Massachusetts. According to a 1647 law passed by the Massachusetts legislature, communities of fifty families or more were required to provide for the education of their children through the establishment of schools. The construction of the Red Brick School in 1807 marked the first offering of secondary education in the community, reinforcing the education that local youth received in grammar schools.

Located on North Main Street, the Robert Carleton House is one of the oldest surviving dwellings in Piscataquis County. Its later Federal style was a sophisticated choice considering this area was newly settled at the time it was built. The house is rectangular and two-and-a-half stories high. The central door is framed by sidelights and pilasters with an entablature displaying intricately carved fretwork. The house likely had a substantial central chimney that has since been removed. During the early 1800s milling became a significant industry in the area.

Located in the village of Goodwins Mills in Dayton, the Levi Foss House features the Federal style with later Greek Revival-style additions. The timber-framed dwelling is one story with a gable roof and a side ell that includes a shed and barn. The entire structure is sheathed in clapboard siding except for the rear wall of the ell which has wood shingles. The central front entrance is contained in a pedimented vestibule and is framed with pilasters and sidelights. Other features include a Greek Revival-style cornice at each end of the barn and moldings around the windows.

Likely the oldest surviving meeting house of the Society of Friends in Maine, the Casco Friends Meeting House is a modest one-story building sheathed in clapboards. The roof is front gabled and there is a small lean-to projection on the south elevation that contains the entry. Two small windows sit in the center of the facade, one in the gable. All trim is plain and the building contains no ornamentation except for narrow cornerboards and cornice returns.

Developed around a ferry crossing on the Kennebec River, Days Ferry is an intact rural late eighteenth- and early nineteenth-century village. This area of Woolwich was initially settled by European-Americans in 1638 and a trading post was established by Richard Hammond. The post was destroyed in 1676 during King Philip's War and was not rebuilt. The ferry between Woolwich and Wiscasset was in operation by 1750 with the Day family in charge of it in the 1780s.

Designated a National Historic Landmark, the Lady Pepperrell House is an excellent example of the High-Georgian style in New England. It is two stories high, sheathed in clapboards, with a hipped roof. The facade is symmetrical and dominated by a full height projecting center bay that contains the entry. The entry is sheltered by a hood molding supported by large brackets. Between the brackets and over the door is a panel carved with a delicate vine motif. Rising on either side of the door are fluted Ionic pilasters that support a pediment.
