1981 photo of the exterior of the Panoramic Corporation, 1405 Riverside Street, on the site of Janesville's first woolen mill, Rock River Woolen Mills (originally known as Whittaker's Mill). The woolen mill was one of the first industries in Janesville to make use of the Rock River's waterpower. The site may hold the distinction of being the longest continually occupied industrial site in Janesville. As of 2005, the Panoramic Corporation had moved to 1400 n: Parker Drive.
