Torre Insignia (also called Torre Banobras and the Nonoalco Tlatelolco Tower) is a building designed by Mario Pani Darqui located on the corner of Avenida Ricardo Flores Magón and Avenida de los Insurgentes Norte, in the Tlatelolco housing complex in Cuauhtémoc in Mexico City.

The building has a triangular prism shape and was built with a reinforced concrete frame.

It has been remodeled at least twice and houses one of the tallest carillon in the world, with 47 bells made by Petit & Fritsen.

With the space requirement and due to rising incomes in the city, the buildings were thought to be in a strategic area, and with this in 1959 construction began with completion by 1962.

It remains a challenge for this area as it is in a seismic zone, which was the fourth building in Mexico City and in the world with Torre Anahuac, Edificio El Moro, and Torre Latinoamericana in counting the latest technology in terms of earthquake shocks, thereby starting four of the great buildings of Mexico City.
