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. It has been remodeled at least twice and is one of the most important buildings in the city, besides having the tallest carillon in the world; there are 47 bells made by Petit & Fritsen.
It is shaped like a triangular prism. The building has become an icon of Mexico City and especially the Avenida Insurgentes Norte. The logo of the station of Metro Tlatelolco carries the silhouette of the building. The station is located very close to the building on the Avenida Manuel González.
The skyscraper's total floor area is 22,033 square metres (236,806 square feet)
