Located in the town of Smithfield, the Kromberg Barn is a transitional agricultural structure that embodies two distinct periods of barn construction.

The house that Captain John T. Plummer first constructed circa 1842 was all but indistinguishable from the two houses north of his on Pleasant Street: all three were one story, side gable, five bay braced frame structures almost identical in terms of massing and plan. All three were essentially vernacular structures that featured Greek Revival style decorative central doors framed by almost identical sets of sidelights and top lights and ornamented with narrow pilasters and capitals.

Forest Lodge is a compact cluster of historic buildings which is almost as isolated in time as it is geographically from the rest of the state.

The Surry Town Hall is a structure that has served as a community building, church, and as the location of the Town of Surry?s governmental functions since 1844. It was originally built in East Surry as the Town House in 1828, but was later sold to the Union Meetinghouse Society and moved into Surry Village. The town retained use of the building during this period, and after it ceased to be used as a church reverted back to municipal functions. Since 1983 the building has been the home of the Surry Historical Society.

The Soldiers Memorial Library is a one story, eclectic style building designed by the Boston architects Robert H. Wambolt and Amos A. Lawrence in 1914.

The building is owned by the Town of Hiram and administered by a Board of Trustees. Within the realm of libraries in the state, the Soldiers Memorial Library is notable as one of only two constructed of ornamental concrete block.

Cliffwood Hall is a structure that has served as a community building, entertainment and recreation venue, and as the location of the Town of Clifton's governmental functions since 1892. It was originally built by a group of local residents, the Band of Willing Workers, as a hall for socials, entertainment and meetings. Seven years later, the Town of Clifton purchased the Hall, and for the next nine decades it continued to serve its original function while also providing offices for town officials and space for the Town's annual public meetings.

Constructed in 1863 as the District #3 school, the Harold Allan Schoolhouse is the last surviving one-room educational facility in this Penobscot County community. In 1912, as the population of the town decreased and shifted, the school was moved about a quarter mile to its current location, adjacent to Cliffwood Hall (Town Hall) at Clifton Corners. At that time a wood shed and outhouse were added to the side of the building and a new vestibule attached to its facade. The Harold Allan School continued to be utilized by the community through the end of the spring term in 1966.

Rivercroft Farm is an extensive agricultural complex with a long history. Home to seven generations of the Weston family, the farm was established in the early nineteenth century.
