They are also historically significant as examples of early 20th century philanthropy, especially notable in a rural county of about 40,000 people. Henry St. Clair and his wife funded the Memorial Hall, and Andrew Carnegie and a local organization funded the library.","narrative":"Two civic buildings share a park-like block in Greenville, Ohio: the Carnegie Library, built in 1901, and the Henry St. Clair Memorial Hall, built in 1910. The library is tan brick with a clay tile hipped roof and a pedimented central portico with a Palladian-style doorway. Memorial Hall has a recessed colonnade of engaged Ionic columns, large arched stained glass windows, a brick and limestone parapet and a slate roof. A rear addition and some replacement windows are the main changes. Both buildings sit well back from the street, softened by trees and landscaping. They are valued as the only body of monumental architecture in Darke County. They also reflect the philanthropy of their era. Henry St. Clair, a wealthy wholesale grocer, and his wife gave $135,000 toward the hall and $3,650 for reference rooms and stained glass at the library. Carnegie and a local organization provided the library's main funding. The hall is described as the high point of that giving.","period_of_significance":"1900-","architect_builder":"Library: W.S.
