It takes in late 19th-century mansions, the Saratoga Race Track property and the Yaddo estate.","why_significant":"The nomination argues that the district holds a homogeneous group of late nineteenth-century mansions tied to the prosperity the Race Track brought. It also includes the oldest continuously operating race track in the United States and Yaddo, the artists' retreat founded by Spencer and Katrina Trask. The district also shows the evolution of Victorian architecture from the 1830s to 1900 and fostered the early growth of Skidmore College.","narrative":"Union Avenue in Saratoga Springs, New York, is a broad, tree-lined street running about a mile and a half east from Congress Park to the Adirondack Northway. Large Victorian mansions with towers, turrets, verandas and shingled or half-timbered detail line the street, and fourteen are described as classic Queen Anne examples. Others show colonial or Italianate details. The district also includes the Saratoga Race Track, whose turreted grandstand and more than 200 structures date from 1864 onward. It ends at Yaddo, a castellated stone mansion built in 1892 by Spencer and Katrina Trask, which became an artists' retreat. The avenue developed as a seasonal resort for the socially prominent, and prosperity from the track supported its houses. Skidmore College later took over many homes as dormitories and classrooms. The district was listed for its architecture, the history of American horse racing, and the artistic legacy of Yaddo. Six buildings are noted as intrusions.","period_of_significance":"1800-1899 and 1900- (the 1800s and 1900s boxes are checked)","architect_builder":"R.
