Millionaires' Mile is the old nickname for the Delaware Avenue Historic District, the west side of Delaware Avenue, New York State Route 384, from North Street to Bryant Street, whose great houses now face you. When it was listed on the National Register of Historic Places in 1974 the district encompassed seventeen contributing buildings and one contributing structure, a stretch long nicknamed the 'Millionaires' Mile.' The great houses you see were built between about 1890 and World War I and deliberately reflect Renaissance Revival and Gothic Revival style architecture. Look to specific addresses and you’ll find stories in stone and glass: 599 Delaware Avenue, the former Temple Beth Zion (1890–1961) by Kent, with Tiffany stained glass (currently 805 Delaware Avenue); 672 Delaware, the Williams-Butler House of 1896 by McKim, Mead & White; 690 Delaware, the Williams-Pratt House of 1896 by McKim, Mead & White; 724 Delaware, the Westminster Presbyterian Church of 1859 by Harlow W. Wilcox; 786 Delaware, the Clement House of 1914 by Edward Brodhead Green, now the Greater Buffalo American Red Cross Building; and nearby, 800 Delaware, the Mrs. Seymour H. Knox House.
