The Prayer Tower is a late Googie design-influenced tower located on the campus of Oral Roberts University in Tulsa, Oklahoma. The 200 ft (60.9 m) glass and steel structure, designed by Tulsa architect Frank Wallace, opened in 1967. An enclosed observation deck gives a 360° view of the surrounding area and enables a self-guided visual tour of the ORU campus. The landscaped Ralph L. Reece Memorial Gardens surround the tower base. The tower is a popular local tourist attraction.
