It has brick walls with Bedford stone detail and mottled red tile roofs.","why_significant":"The nomination argues it is architecturally unique in Dayton, a high-rise with Early Italian Renaissance detail that joins the Art Institute and Masonic Temple in shaping the river front. It is also significant in social history for the YMCA's contribution to the Dayton community, including its pioneering vocational education program.","narrative":"Rising fourteen stories above Dayton's river front, this 1929 YMCA building combines a central shaft, two twelve-story residential wings, social wings, an entrance block with auditorium, and a rear athletics block containing a natatorium and two gymnasiums. Tan brick, Bedford stone detail and mottled red tile roofs give it a Mediterranean character with Early Italian Renaissance ornament. Schenck and Williams, Dayton's largest architectural firm of the era, designed it with the YMCA's national architectural bureau. It was listed for its distinctive design and for social history. The Dayton YMCA began educational work in 1887, and its vocational program was the first of its kind in the national movement. Sinclair College was formed in the building in 1946. Original features survive, including the chapel, auditorium, natatorium, a central courtyard with fountain and Shepard traction elevators. The building continues to serve community needs, including health care.","period_of_significance":"1929","architect_builder":"Schenck and Williams, Architects (with the Architectural Bureau of the National Council of the Y.M.C.A.)","architectural_style":"Italian Renaissance (Mediterranean style with Early Italian Renaissance detail)","criteria":["A","C"],"status_note":"Still in use for social, religious, educational, athletic, residential and medical purposes; surplus space houses chemical dependency in-patient care and a mental health clinic.
