It also includes churches, schools, lodge halls and a public park known as the Diamond.","why_significant":"The district is significant under Criterion A for its association with local and county government, anchored by the Butler County Court House, and with the commercial life of the city, including its growth during the regional oil and gas boom. It is also significant under Criterion C for its concentration of buildings in a range of styles from the 1820s through the 1950s, including works by named architects and builders.","narrative":"Butler's central business district occupies about forty-six acres on a ridge in central Butler County, roughly forty-three miles north of Pittsburgh. Its buildings date from the 1820s through the early 1950s and include storefronts, churches, lodge halls and schools, with most commercial blocks built of masonry. The town was laid out in 1828 and became the county seat, and its Court House, completed in 1885, anchors the district. Downtown grew with the oil and gas boom that began in 1859, and later with the railroad, steel and rail car manufacturers that followed. Architects and builders represented in the district include Harry Wimer, F. J. Porter and the New York firm of Mobray & Uffinger. The collection shows the sequence of styles from Greek Revival through Art Deco, and it documents how government, commerce and institutional life shaped the town's downtown.","period_of_significance":"c. 1828-1952","architect_builder":"Harry Wimer (master builder); F.
