Originally located on the other side of Main Street and further to the south, the Squire Chase House was built in the Federal style but was later remodeled in the nineteenth century with Italianate-style characteristics. The dwelling is two stories high with clapboard siding and a hipped roof. Attached is a long ell connecting to a barn-both with gabled roofs. The front facade is symmetrical with a central entrance framed by red glass sidelights and topped with a fanlight. The Italianate-style elements include the bracketed cornice and ornate rectangular cupola.

This McCobb-Hill-Minott House, located on Parker Head Road, is an exquisite Georgian style house with a hip-roof and central cupola sitting between two chimneys. The two-story dwelling has clapboard siding with central doors on both the southwest and northwest facades. Both entryways are framed by Doric pilasters and topped by a triangular pediment. Originally from Ireland, James McCobb came to the area in 1731. He gained considerable wealth in both lumber and commerce and built the house after acquiring roughly 1,000 acres.

Though currently located in the central business district of Portland, when first completed, the Wadsworth-Longfellow House had nearly unobstructed views of the Portland Harbor and the Back Cove. The building sits back from the street behind a cast-iron fence and a brick courtyard. It is three stories high, constructed of brick. The symmetrical facade contains little ornamentation except the arched windows on the first and second floors and the entry porch sheltering the door. Doric columns support a projecting pediment that covers a simple wood paneled door.

The remnants of Fort George are physical reminders of the military conflicts in Maine prior to its statehood. Because the town of Castine occupies an important strategic position at the head of Penobscot Bay, British forces seized the town in June 1779 and built Fort George to establish their control over the lumber-rich region, which they renamed New Ireland.

Set on a rise above the Stroudwater River, the George Tate House is two-story Georgian-style structure. It is clad in unfinished clapboards and has a massive center chimney. The facade is symmetrical and a one-story ell extends off the east elevation. The centered entry door is framed by heavy pilasters supporting a pediment. The windows are made up of multiple small panes. The house's most unique feature is its roof: the gambrel form is recessed in front at the break in pitch and three small windows allow light into the attic behind them.

Located southwest of downtown Hallowell, the Elm Hill Farm consists of a farmhouse, garage, storehouse, and barn with farm fields interspersed with fences and hedges. The farmhouse is a modest dwelling with a side-gabled roof, two interior end chimneys, gabled dormer, and a central entry. The dormers and interior chimneys were added later to create additional space in the upper story. John Merrick constructed the house in 1799 upon his return to Hallowell from England after marrying Rebecca Vaughan.

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.
