The Berea Historical Society seeks to preserve and share the history of Berea and Middleburg Township, Ohio. To this end, the society sponsors the Mahler Museum & History Center, housed within an 1854 sandstone residence. The History Center includes exhibits and the historical Gray's Candy Kitchen, while the museum focuses on period rooms. The history of Berea is largely dependent on the discovery of area sandstone veins.

The museum offers exhibits, period rooms, guided tours, and an archival resource room.
