Built c. 1910 by Maine businessman Amos F. Gerald, the house is notable both for its architecture, which is best described as resembling a medieval castle, and for its association with Gerald, who was a major proponent of electrification in the state, and who built many of the state's (now defunct) trolley systems.

[1] The Gerald House is set on the northwest side of Main Street (United States Route 201) on the fringe of Fairfield's central business district.

It is a two-story building with a prominent centrally-placed three-story round tower that has a crenellated parapet.

The building is fashioned out of concrete blocks that are finished to resemble rusticated stone.

Surrounding the tower on the front is a single-story porch supported by thick columns, also fashioned out of concrete blocks, and sporting a crenellated parapet.
