We visited several sites in the Pittsburgh metropolitan area. The Carrie Furnaces, located in Rankin, PA, are a series of archaic blast furnaces operated by US Steel and shut down in 1982. The site is now preserved as a historic site, managed by the Rivers of Steel Heritage Corporation. The Husler Building in Carnegie, PA was built through financing from a local physician, Dr. Husler in 1896. The lower level was an early A & P Market, while an upper level housed The Star Theater which opened in 1905, and a dancehall, and later a rumored speakeasy opened during Prohibition. The Yellow Dog Workers' Village was built by the Limestone Mining Co. as housing for its employees from 1915-1925. It was mostly abandoned within the last 2 decades. The exodus was quite abrupt as you can see in some of the images. Finally, we explored some downtown sites where there was a juxtaposition of the old and new.
