Walter, with later additions in 1893 and 1966.","why_significant":"The nomination argues the courthouse has remained a monument of its time despite later alterations, and is a model of the integration of design and structure. Its vaulted brick and stone construction and Greek Revival design, including the cupola used as a clock tower, are presented as its key distinctions. It is also one of several Walter buildings in West Chester.","narrative":"Built in 1846 to designs by Thomas U. Walter, the Chester County Courthouse in West Chester is a brick and stone structure whose original section measured 62 by 119 feet. Its basement and first-floor offices are covered by double-domed brick vaults, and an oval two-story hall sits behind the portico. The east side features a hexastyle Corinthian portico with cast iron columns, and an elongated cupola rises above the facade, serving as a clock tower. Walter's design balanced the building's public importance with the Greek Revival idiom, reinterpreting the Baroque cupola in a form compatible with Greek precedent. The building is regarded as a model of the integration of structure and design. An 1893 limestone addition by T. Roney Williamson and a 1966 section have been attached since, but the original Walter work is considered by far the most significant part of the complex.","period_of_significance":"1846-1848","architect_builder":"Thomas U.
