It was built in 1923 on the site of the Trinity Methodist Church, which had been erected in 1869 and was demolished in 1922. The new mercantile and office block cost $125,000 and was designed by the Springfield firm of Samuel M. Green Co. Its facade is notable for cast stone and brightly colored terra cotta, with color emphasizing the vertical and horizontal elements between bays. The cornice combines arches with abstracted dentils, keystones and other Classical motifs. Storefronts were rebuilt in the mid-twentieth century, though the original spacing and many transom details survive. Early tenants included the Dietz Bakery, whose successor company kept its general offices here, along with a dress shop, tea room and furrier. The building was listed for its architecture and for its role in the growth of downtown Springfield as a commercial district.","period_of_significance":null,"architect_builder":"Samuel M. Green Co.
