The Kerst-Bertolet Mill in Oley, Berks County, Pennsylvania. The earliest mill built on this land was built by Johann Heinrich Kersten in 1725. Kersten shortened his name to Kerst as many immigrants did to make for easier pronunciation. The current mill was built in 1841, a 40'x 55' limestone mill standing 3.5 stories and covered with stucco. The head race is fed from Manatawny Creek and the tail race empties into the pond.
