Mullendore Mansion, Greek Revival mansion in Cleveland, Oklahoma

The Mullendore Mansion is a two and a half-story structure built in Greek Revival style, rising on a hilltop above the Arkansas River. The building displays typical features of this architectural approach, including broad columns across its facades and balanced proportions that make the residence a notable example of early twentieth-century residential design.

E.C. Mullendore, an influential rancher and banker, commissioned the mansion's construction in 1910 and lived there until his death in 1938. The residence emerged during Oklahoma's early development, when agricultural wealth shaped the region's architecture and society.

The mansion embodies the architectural language of the early 1900s, showing how wealthy ranchers lived during this era. The symmetrical facades and tall columns reflect the taste and status of a family that shaped Oklahoma in its formative years.

The mansion stands on 16 acres overlooking the Arkansas River in Cleveland, Oklahoma, in Pawnee County. It is reached by road from Cleveland, with Pawnee to the northwest and Tulsa to the southeast as the larger reference points. The grounds are private property, so access to the house and land depends on the owner's arrangements.

The mansion was built in 1910 on 16 acres overlooking the Arkansas River, and E. C. Mullendore lived there until his death in 1938. The property was listed on the National Register of Historic Places in 1984.
