Bagdad’s historic buildings reflect the village’s history, cultural heritage, and changing periods of growth, with architectural styles ranging from Greek Revival in the 1840s to bungalows in the 1920s. Most homes were built by mill owners, and each change in mill ownership brought a surge of construction in the style then in favor. During the E. E. Simpson period from 1855 to 1866, Greek Revival was popular, though few buildings from that era survive because most of the village was destroyed during the Civil War. From 1866 to 1903, wood-frame Creole and Gulf Coast cottages were dominant. During the Stearns and Culver era from 1903 to 1923, Chicago-based owners used a few basic house plans, including the Four-Square, Saltbox, and a two-story duplex called the Double House. During the Bagdad Land and Lumber Company period from 1922 to 1939, mill expansion led to the construction of shotgun houses for workers and bungalows for superintendents, many of whom lived along Main Street. Among the oldest houses in Bagdad is the Thompson House at 4620 Forsyth Street, built in the late 1850s by Benjamin W. Thompson as a fine example of Greek Revival architecture, with interior door facings in the Egyptian Revival Temple of Luxor design. In October 1864, Union troops under Colonel Andrew Spurling camped in the Thompson House and left graffiti on the parlor and upstairs hall walls that can still be seen today.
