Citigroup Center was completed in 1977 at 279 m. containing 59 floors with 1.3 million square feet of office space (wikipedia).
Base of the Citigroup Center. St. Peter's Evangelical Lutheran Church is visible on the left-hand-side below the skyscraper, the location of which necessitated the unusual column locations (wikipedia).
