The Maine General Hospital West Pavilion, completed in 1892, included the Resident Superintendent's house at the left. The holder of that position resided in the house into the 1950s.

On the roof of the West Pavilion was one of the building's five cupolas of varying size, symmetrically arranged in a gothic style. Maintenance costs for these decorative features and the filigree ironwork that was part of the original roofline were considerable. The larger cupolas on each pavilion were removed in 1954, while the cupola atop the central building's signature tower is the only one remaining.
