It centers on the Brown's Race millrace and nineteenth-century factory buildings, structures and archaeological sites.","why_significant":"The district preserves rare survivals of Rochester's nineteenth-century industrial heritage, including the last visible water-filled raceway in the city and an in situ overshot water wheel at the Triphammer site. Its masonry mills and factories show the shift from waterpower to steam and electric power. The form also cites high archaeological potential beneath parking lots and former mill sites.","narrative":"Brown's Race Historic District occupies an industrial corner of Rochester beside the Upper Falls of the Genesee River gorge. It includes 15 contributing buildings, 2 contributing structures and 14 contributing sites, mostly brick and stone factories from the nineteenth century. Notable examples include the six-story Romanesque Revival Gorsline Building, the High Victorian Rochester Water Works, the stone Selye Fire Engine Factory and the former Rochester Button Factory buildings. The structures include the open stone-lined millrace, thirty feet wide and five feet deep, and the iron truss Platt Street Bridge, now used by pedestrians. The district matters because it holds rare surviving evidence of Rochester's milling and manufacturing past. The race is the last visible water-filled raceway in the city, and the Triphammer site contains an overshot water wheel still in place in its pit. Parking lots over vanished mills add high archaeological potential.","period_of_significance":null,"architect_builder":"Matthew Brown and the Brown brothers (Triphammer)","architectural_style":"Late Victorian: Second Empire and Romanesque","criteria":[],"status_note":"Principal buildings are used for commercial purposes; the form lists current functions including industry, warehouse, business and vacant/not in use.
