The Oolagah Historical Museum features artifacts reflecting everyday area life from turn-of-the-century to present day.

The front part of the museum building has its roots in the 1890s, and is believed to be the oldest commercial building in the downtown district. It was originally Mart Reed's General Store. The building was restored and opened as the Oolagah Historical Museum in 1988. The room is decorated as a Victorian front parlor and features photographs and items from pioneer Oologah families.

The large exhibit hall behind the front room was added in 1992. Exhibits are grouped by theme and include farm and ranch, military, school, home, childhood, Will Rogers, business life and early town government. The museum also has some early tax records and other books available for research.

A painting by Claremore impressionist Gary Moeller, portrays Will Rogers and downtown Oologah in the early days. Posters and art prints featuring the painting are available. A gift corner features Oologah memorability, postcards and books.
