Nathaniel Treat House

The Nathaniel Treat House is set on the east side of Main Street (United States Route 2), just north of its junction with Westwood Drive. It is a 2+1⁄2-story brick structure, with a side-gable roof, four symmetrically placed end chimneys, and a five bay front facade. The main entrance is centered, with a sheltering portico supported by fluted Doric columns and pilasters, whose interior has been glassed in. The doorway is slightly recessed in the wall, with flanking sidelight windows, and a half-round fanlight above. Fenestration is all sash windows, with granite sills and lintels in front. A dentillated cornice encircles the building below the roof line. A single-story open porch extends along the south side of the house.[2]

Nathaniel Treat was one of the leading businessmen of the Orono-Old Town area, in the mid-19th century. He moved to the area in 1829, established a series of sawmills, and acquired much of the land that now makes up the two cities. He was one of Orono's first town selectmen, and served in the state legislature. This house was probably built not long after his arrival, and was his home for about thirty years. In 1924, the house was purchased by Irene Dunn, wife to Charles J. Dunn, then an associate justice of Maine's highest court. Dunn served on the Maine Supreme Judicial Court from 1918 to 1939, the last four years as chief justice.[2]
