Built in 1922–23 to a design by Hutchins & French of Boston, Massachusetts, it is historically significant for its role the city's education, and architecturally as a fine example of a "modern" high school building of the period with Colonial Revival styling.

[1] The Old Kennebunk High School is located on the southeast side of Park Street, roughly opposite its junction with Dane Street, on the south side of the village center of Kennebunk.

The central five bays are demarcated by pilasters, and have large sash windows on the second level.

The original main entrance stands in the center bay, with a transom window and console hood above.

Modern additions dating to 1954 and 1962 extend the original building to the rear.
