The buildings are commercial structures dating from the late 19th and early 20th centuries.","why_significant":"The district records the shift of Prospect Avenue and Huron Road from residential streets to a commercial center, with department stores, office blocks, banks, hotels and garages. It also holds a fine collection of architectural terra cotta facades and buildings by many notable Cleveland architects.","narrative":"This group of downtown Cleveland buildings extends the Lower Prospect/Huron Historic District to the south and east. The district centers on Prospect Avenue and Huron Road, which cross at East 9th Street in a five-point star that produced irregular, wedge-shaped buildings such as the Flat Iron and Osborn buildings. The structures range from one to 22 stories and are built of brick or steel frame, with many faced in glazed terra cotta. Most were designed by architects. They record how large homes along these streets gave way to commerce after 1900, when developers promoted the intersection as a new business center. Notable examples include the Rose Building, the Halle Bros. department store additions, the Ohio Bell Telephone Building of 1927, and the Hotel Winton with its companion garage on Bolivar Road, later converted to offices. Three altered buildings are counted as noncontributing.","period_of_significance":null,"architect_builder":"Various, including George A. Grieble, George H.
