The architecturally distinctive building was designed by the Lewiston firm of Gibbs & Pulsifer, and was built in 1926 as a gift from Lewis Mann in honor of his son Arthur.

The most prominent section is the crenellated tower, which projects forward and left of the bulk of the building, and has three narrow casement windows on the front, staggered in height.

To its right, in the center of the main facade, is an arched entrance bay, topped by an elevated parapet with crenellations and flanked on the right by a narrow casement window and a buttress.

[2] The interior has a fairly conventional library layout, with a central circulation desk, a reading room to the right, and stacks to the left.

Lewis Mann, a longtime West Paris resident, bequested land and funds (the latter matched by his son Edwin) for this building, which was completed in 1926.
