The Canadian County Historical Society and Museum is located in the original Rock Island Depot.  Throughout the past 50+ years the Canadian County Historical Society that supports the Museum has rescued several buildings from demolition by moving them to the Museum property at Heritage Park. The Museum collections on display include railroad memorabilia, early pioneers and settlers, Fort Reno, Darlington, and Indian exhibits.

The Canadian County Museum is rated as one of the outstanding museums in Oklahoma.  It is open five days a week from Wednesday through Sunday.  The museum is located in El Reno’s historical Heritage Park which is on the 98th Meridian which was the division line between the Unassigned Lands in Central Oklahoma and the Cheyenne Arapaho Lands in Western Oklahoma.  Thus, it was the West Boundary in the Run of 1889 and the East Boundary during the Run of 1892.  The main Museum is in the old Rock Island Railroad Depot.
