Cherry Grove Old Home and Community Day


The 646 Mystery Well celebration is canceled for 2020, due to public health concerns stemming from the COVID-19 virus. We plan to hold our annual event again in June of 2021.

Located in southern Warren County, in the Pennsylvania Wilds, the hilltop settlement of Cherry Grove made national history in the Spring and Summer of 1882 when the Mystery Well on Lot # 646 ushered in a great oil boom. In a matter of months, hundreds of oil wells were drilled and a town sprang up in this isolated township in the hills.  Before the railroad could lay a new line to Cherry Grove, the boom went bust. Thousands of people moved on. Those who remained kept the memory of the Oil Excitement alive with reunions that became known as “Old Home Day”.

In 1982, a group of Old Home Day regulars volunteered to build a replica of the historic 646 Mystery Well. That spring and summer, the volunteers completed a life-size 1882-style oil derrick and shanty in time for the Centennial celebration. In preparation for the 125th anniversary in 2007, volunteers came together once again to rebuild the Replica of the 646 Mystery Well. The volunteers worked with the township supervisors to secure grants and bring in a work crew from the Pennsylvania Conservation Corps.

This annual event is open to the public.  Anyone who is interested in Warren County history, oil field history, or Cherry Grove Township, is encouraged to participate to keep the history alive.

Details on the location and planned activities for the 2021 event will be posted to this web-site and to our Facebook page as they become available.
