 Commercial and civic buildings from the early period of growth, and of a second spurt of growth after the American Civil War survive in the center, including the Romanesque Winchester Town Hall (1887), and the 1879 Brown and Stanton Block at Main and Mount Vernon Streets.Growth continued in the early 20th century, with the Beaux Arts Lincoln School (1903), the Colonial Revival Police and Fire Station (1914), and the Gothic Revival library (1931), designed by local architect Robert Coit.The most significant ahistorical modification to the district is the elevation of the Boston and Lowell line, effectively bisecting the district.
