110 West 7th Building

The 110 West 7th Building is a commercial skyscraper in downtown Tulsa that rises 28 stories with a striking black and white grid pattern across its exterior facade. The geometric design covers the entire height of the structure and creates a distinctive visual rhythm visible from street level.

The building opened in 1971 as the headquarters for Cities Service Oil and Gas Corporation, an energy company that relocated its operations from New York to Tulsa. This move represented a major economic shift that brought significant employment to the region.

The building reflects the International Style architecture movement of the post-World War II period, emphasizing clean lines and functional design in urban structures.

The building has ten passenger elevators and one freight elevator serving the entire 28-story structure. These systems allow efficient movement of people and goods throughout the building.

The structure ranks as the seventh tallest building in Tulsa and maintains its position as the fourteenth highest structure in the state of Oklahoma.
