Torre Insignia (also called Torre Banobras and the Nonoalco Tlatelolco Tower) is a building designed by Mario Pani Darqui which is located on the corner of Avenida Ricardo Flores Magnon and Avenida de los Insurgentes Norte, in the Tlateloco housing complex in Cuauhtémoc in Mexico City. At its completion in 1962, the tower became the second tallest building in Mexico after the Torre Latinoamericana. The tower is not currently in use and is currently being renovated. It is currently the tallest building in the Tlatelolco area and the third highest in the Avenida Insurgentes. The building housed the headquarters of Banobras. The building has a pyramid shape and was built with a reinforced concrete frame.
