Hancock Whitney Center, formerly One Shell Square, is a 51-story, 697-foot (212 m) skyscraper designed in the International style by Skidmore, Owings and Merrill, located at 701 Poydras Street in the Central Business District of New Orleans, Louisiana. It is the tallest building in both the city of New Orleans and the state of Louisiana, and is taller than Louisiana's tallest peak, Driskill Mountain. The building is primarily used for leasable office space, with some retail space on the ground level. The design of the building is very similar to Houston's One Shell Plaza and Denver's Republic Plaza, as well as Rochester's Five Star Bank Plaza, all designed by Skidmore, Owings and Merrill. Hines Interest is the developer of Hancock Whitney Center and Lincoln Property Company. Shell Oil Comp
