Amoco Building, Office tower in Central Business District, New Orleans, United States

Orleans Tower, formerly the Amoco Building, is a 20-story, 280-foot (85 m) skyscraper at 1340 Poydras Street in New Orleans' Central Business District. Designed by 3D/International in the International Style, it has a black aluminum and glass curtain wall and is mainly leasable office space, with some retail on the ground floor.

Orleans Tower was built in 1977 as the headquarters of the oil company Amoco, which is why it was long known as the Amoco Building. It was designed by 3D/International in the International Style, with a black aluminium and glass curtain wall. It now houses city and state agencies, including the Orleans Parish District Attorney's Office.

The tower's black aluminium and glass curtain wall follows the International Style that Mies van der Rohe set with the Seagram Building in New York and Skidmore, Owings and Merrill with the Sears Tower in Chicago. Completed in 1977, it is cited as one of the earliest examples of that style in the United States.

The building features accessible retail spaces on the ground floor and is centrally located within the business district. Modern amenities including multiple elevators make it easy to navigate the structure.

Built in 1977 as the headquarters of the oil company Amoco, the tower later took the Orleans name and now houses the Orleans Parish District Attorney's Office among other city and state agencies. Its black aluminium and glass curtain wall follows the International Style model of Mies van der Rohe's Seagram Building.
