Riddle.","why_significant":"The nomination calls it the last of nine surviving Riddle commercial buildings erected between 1870 and 1914 and one of the larger, more elegant ones. It is described as an unusually fine example of Neoclassical commercial architecture and one of the community's largest downtown buildings. It is also tied to Henry Warner Riddle, who played an important role in the town's growth.","narrative":"Riddle Block #11 is a three-story brick commercial building at the northwest corner of East Main and Prospect streets in Ravenna, Ohio. Completed in 1914, it was the last of nine surviving commercial buildings put up between 1870 and 1914 by H.W. Riddle, a local businessman and carriage manufacturer. The building has a central parapet that carries its name, brick pilasters linking the second and third floors, and a broad stone entablature that wraps around the structure. Stone voussoirs accent the windows. The ground-floor storefronts have been modernized, though their basic structure remains largely intact. It stands at the eastern edge of downtown, across from the surviving Riddle Carriage Factory buildings. The block is considered an unusually fine Neoclassical commercial design and one of the largest downtown buildings. It reflects a period when American communities were being reshaped by more restrained, academically inspired architecture, and it is linked to Henry Warner Riddle's role in the town's development.","period_of_significance":null,"architect_builder":null,"architectural_style":"Neoclassical","criteria":["A","B","C"],"status_note":"Interior and exterior condition are listed as good; the storefronts have been modernized but retain their basic structure.
