The Mills and Hale Blocks were built in 1874 and the Owen Block in 1899, each with stores at street level and tenements above.","why_significant":"The blocks are argued to be significant for their role in the late-nineteenth-century commercial development of Springfield's South End and for their architecture. The Mills and Hale Blocks are described as two of the finest remaining Italianate commercial blocks in the city and the oldest commercial buildings on Main Street in the South End. The Owen Block is a good example of a small turn-of-the-century commercial block with Classical Revival detailing.","narrative":"Three adjoining brick buildings on the east side of Main Street in Springfield's South End make up the Mills, Hale and Owen Blocks. The Mills and Hale Blocks were built in 1874 by local carpenter and builder Warren Mills, at a combined cost of $50,000. Both are three stories with pressed brick facades, arched upper windows and projecting tin cornices. The four-story Owen Block, built in 1899 by Frank E. Owen for $30,000, is faced in yellow brick with brownstone trim, Ionic pilasters and Classical Revival detailing. Each building had shops at street level and boarding rooms or tenements above, occupied by grocers, druggists, laundries, furniture dealers and neighborhood families. Main Street had been residential until after the Civil War, and these blocks were among the first of the mixed-use brick buildings that transformed it. The Mills and Hale Blocks are the oldest commercial buildings on Main Street in the South End. At the time of listing, the buildings were largely vacant and being rehabilitated as apartments.","period_of_significance":null,"architect_builder":"Warren Mills (Mills and Hale Blocks); Frank E.
