The Queen Anne style building with Renaissance Revival details was designed by the Portland architect Francis H. Fassett, and was used to house inmates through the mid-1970s. The front half of the facility is a comfortable residence, featuring period detailing, while the back half contains fourteen small granite cells on two levels.

The Lisbon Falls High School is a notable example of Romanesque Revival architecture, located in the relatively small industrial town of Lisbon, Maine. The brick school, with finial topped tower, arched windows and doors, and terra cotta and granite accents, was the work of William R.

The Common in Union is a town-owned green space that has been a community resource since 1790. Surrounded by nineteenth- and twentieth-century homes, businesses and civic buildings, the Common was initially set aside by the fledgling community as a shared plot of land on which residents could pasture their livestock, gather, and hold military training. Landscape improvements occurred throughout the nineteenth century, first with the removal of ledge and later with the planting of elm trees. After the Civil War the Common was the site chosen by the local G.A.R.

The Albany Town House is one of only three historic public buildings in Albany Township, Maine. It was built in 1848 by the residents of Albany for use as a polling place, town meeting site, and the location of governmental activities. Architecturally, it is a vernacular structure with just a nod towards the Greek Revival style. This building served the Town of Albany until the municipality?s charter was forfeited to the State of Maine in 1937, and the town became an un-organized territory under State administration.

As Maine communities began to lose their frontier aspects in the 19th century and assume a more settled countenance, rudimentary civic improvements were initiated. Among these improvements in the largely agricultural world of rural Maine were those concerned with the regulation of livestock. To control the problem of loose cattle, hogs, or sheep towns constructed open air shelters, known as pounds or cattle pounds, to temporarily corral wayward animals. The existence of 21 of these structures in Maine has been verified, and their condition varies from almost unrecognizable to good.
