It holds 30 houses and related outbuildings dating from about 1850 to 1925.","why_significant":"The form describes the district as the largest and most impressive collection of predominantly high-style domestic architecture in the village. It shows a broad range of popular American styles, with grand mansions as focal points. The boundary includes only contiguous buildings that keep a high degree of original integrity.","narrative":"South Main Street in Mount Morris is lined by one of the village's premier residential neighborhoods, and this district takes in both sides of a three-block section. It contains 30 houses, 27 of them contributing, plus 13 contributing outbuildings, mostly carriage barns and garages, and 7 non-contributing buildings. Construction dates run from about 1850 to 1925, with most buildings from the late nineteenth century. Houses are mainly wood-framed, with some brick, and range from one and a half to two and a half stories in Greek Revival, Second Empire, Italianate, Queen Anne, Colonial Revival, Foursquare and Prairie styles. Wide, tree-lined streets and large landscaped lawns frame the buildings. Focal points include a Greek Revival house at 145 South Main with a monumental Neoclassical portico, a Georgian Revival brick house at 140, and a Second Empire double house at 154. The boundary excludes heavily altered or modern buildings, so the district reads as the village's largest and most impressive group of high-style homes.","period_of_significance":null,"architect_builder":null,"architectural_style":"Mid-19th century Greek Revival; Late Victorian Italianate and Second Empire; 20th century Classical Revival, Colonial Revival, Foursquare and Prairie","criteria":[],"status_note":"Mostly single-family and multiple-dwelling residences still in domestic use.
