Now home to the Machias District Court and other county offices, it is an 1853 Italianate brick building designed by Benjamin S. Deane and listed on the National Register of Historic Places in 1976.

[1] The Washington County Courthouse is located at the corner of Cooper and Court Streets in the center of Machias, between the Washington County Jail (to which it is now attached by a modern ell) and the local post office.

First floor windows are set in segmented-arch openings that are surrounded by recessed panels.

The first and second floors are separated by a granite stringcourse, and the second-floor bays are articulated by brick pilasters.

Deane is one of the first professional architects known to be working in Down East Maine, and is also credited with the Waldo County courthouse, a similar transitional Greek Revival-Italianate design.
