Welcome to the Flat River Historical Society and Museum

WE'RE OPEN!   The Flat River Museum is open Saturdays and Sundays from 2:00 to 4:30 pm. We will also be open from 6 to 7 pm prior to Rotary Concerts in the park Thursdays July 8, 15, 22, 29 and August 5.  We will observe current Covid protocols to protect staff and visitors. Keep checking website or Facebook for updates.


"Your journey begins here", proclaims the artwork outside the entry, inviting you to discover how our community came to be and what it is today. Greenville's founder, John Green, built his first cabin at this very spot, knowing that the Flat River nearby was the key to the future development of lumbering, agriculture, industry and beyond. The museum building itself is an artifact, having been used as an egg emporium in the early 1900s!

Inside are three floors of exciting displays depicting the evolution of the area from early times to the present - its topography, its people, its history, its activities!

Outside, stroll through our lovely Victorian garden on the bricks of former city streets as you enjoy the rush of the waterfall and the aroma of flowers. Pause on a bench and let your mind drift back to days gone by! Come, journey with us ... and take home memories to reminisce for a long time.
