What's next
The museum is
getting bigger.
Founded in 1966 inside a 19th-century building downtown, OMSH is in the middle of its next chapter — a new gallery under construction, new programming on the calendar, and a lot more reason to come back than there was last year.
IN CONSTRUCTION
River Heritage History Gallery
An eighth permanent gallery on the Ohio River and the town it built.
GROWING
Weekly drop-in programming
Wonder Wednesday every week, Sensory Mornings monthly, and a teen club that meets after hours.
RETURNING
Voices of Elmwood™ 2026
Four evenings in September at Elmwood Cemetery. Members get early access to tickets.
1966
Founded — and still the only place in town with a coal mine on the second floor.
