The buildings date from 1893 to 1910.","why_significant":"The nomination argues the district is significant for the industrial development of Dayton, because it grew up around a rail spur and the East Third Street thoroughfare and housed varied wholesale and manufacturing firms. It is also significant for architecture, as a well-preserved group of early Commercial style industrial buildings showing Queen Anne, Romanesque and Renaissance Revival influences.","narrative":"Along the south side of East Third Street, just east of Wayne Avenue in Dayton, six brick warehouse and light industry buildings and a brick paver alley form a cohesive group. Built between 1893 and 1910, the buildings rise four to six stories and include the Barney/Throckmorton Building, the Lowe Brothers Paint Company Building, the Canby, Ach and Canby Building and the American Cigar Company Building. The area developed because a rail spur ran behind the lots and East Third Street offered a major route, and it housed wholesale grocers, coffee roasters, tobacco wholesalers, paper distributors and a paint manufacturer. Architecturally, the buildings show the Commercial style, with base, shaft and crown composition and walls of piers and spandrels. Details recall the Queen Anne, Romanesque Revival and Renaissance Revival styles, and later examples use more glass and terra cotta. Original windows, cornices and many storefront elements survive, which supports the district's recognition for industrial history and architecture.","period_of_significance":"1893 to 1950","architect_builder":null,"architectural_style":"Late Victorian: Romanesque; Late 19th and early 20th century revivals: Classical Revival (described in the text as Commercial style)","criteria":["A","C"],"status_note":"Current functions listed include warehouse, business, professional offices and vacant (not in use).
