The story

How Keystone Township came to be

From Wikipedia’s history of Keystone Township.

Read it all →

Keystone was originally built up by settlers from Pennsylvania, and the name taken from that state's nickname, the Keystone State. The beginning of Keystone was about a mile north of where the town was finally established. There was a $3000 (equivalent to $87,941 in 2025) church built in Keystone which was used there as long as the town lasted and then it was moved to Monango.
