Aka Oberholtzer’s Mill / Hurst Brothers Mill
The Spring Grove mill was built in 1793 by Cyrus Jacobs as part of the Spring Grove Iron Forge. The forge closed in 1867 but the mill continued to operate well into the 20th century. Currently the old mill is in fair condition and is used for farm equipment storage.
