Rockland Township was organized in 1758. Prior to that it was a part of Oley. It took its name from the numerous rocks it contains. Boulders thirty feet long, fifteen feet wide and fifteen feet high may be seen. Certain collections of rocks are known as Shott's Head and Guinther's Head. Near the latter there is a succession of rocks one hundred twenty feet long. This is the watershed of the township and from this point the water is drained south, east and west.
