The facade is bordered on the north and south by two towers and includes three main doorways, each of which lead to a different part of the building.
The southern door leads to the Patio of Honor and presidential offices (no public access).
The northern door is known as the Mariana Door, named in honor of Mariano Arista who had it constructed in 1850.
 The area next to this door used to be the old Court Prison, with courtrooms and torture chambers.
It is now occupied by the Finance Ministry.
It contains the Treasury Room, constructed by architects Manuel Ortiz Monasterio and Vicente Mendiola.
The iron and bronze door is the work of Augusto Petriccioli.

Above the central doorway, facing the Zócalo, is the main balcony where just before 11pm on September 15, the president of Mexico gives the Grito de Dolores, in a ceremony to commemorate Mexican Independence.
Part of this ceremony includes ringing the bell that hangs above the balcony.
 This bell is the original one that Father Miguel Hidalgo rang to call for rebellion against Spain.
 It originally hung in the church of Dolores Hidalgo, Guanajuato, but was relocated here.
 In the niche containing the bell, there is the Mexican coat of arms.
On each side there is an Aztec eagle knight and his Spanish counterpart.
These were sculpted by Manuel Centurion and symbolize the synthesis of Mexican culture and Spanish culture.

The central door leads to the main patio which is surrounded by Baroque arches.
Only the balustrade of this area has been remodeled, conserving the murals by Diego Rivera that adorn the main stairwell and the walls of the second floor.
In the stairwell is a mural depicting the history of Mexico from 1521 to 1930, and covers an area of 450 m² (4800 ft²).
These murals were painted between 1929 and 1935, jointly titled "The Epic of the Mexican People".
 The work is divided like a triptych with each being somewhat autonomous.
 The right-hand wall contains murals depicting pre-Hispanic Mexico and centers around the life of the Aztec god Quetzalcóatl.
Quetzalcóatl appears in the mural as a star, a god, and a human being.
Created by serpents, he sails through space as a star that accompanies the sun at night.
Quetzalcóatl then assumes a human body to teach the Aztec people as their king and patriarch.
Last, when he sacrifices his blood to give life to men, he returns to the sky having completed his earthly cycle.
Once he leaves the earth, Quetzalcóatl assumes the shape the morning star, called Tlahuizcalpantecuhtli.
The cycle that he undergoes signifies the continuous cycle of life.
Rivera's creation of a Mexican identity helps to continue the reform that began with the Mexican Revolution of 1910.
Before this time, any individualism from the Indians was discouraged as well as any allusion toward Aztec origins.
The mural aims to dismiss any idea of inferiority.

In the middle and largest panel, the Conquest is depicted with its ugliness, such as rape and torture, as well as priests defending the rights of the indigenous people.
The battle for independence occupies the uppermost part of this panel in the arch.
The American and French invasions are represented below this, as well as the Reform period and the Revolution.
The left-hand panel is dedicated to early and mid-20th century, criticizing the status quo and depicting a Marxist kind of utopia, featuring the persons of Plutarco Elías Calles, John D. Rockefeller, Harry Sinclair, William Durant, J.P. Morgan, Cornelius Vanderbilt and Andrew Mellon as well as Karl Marx.
This part of the mural also includes Frida Kahlo, Diego's wife.
This mural reflects Diego's own personal views about Mexico's history and the indigenous people of the country in particular.

Diego also painted 11 panels on the middle floor, such as the "Tianguis of Tlatelolco" (tianguis means "market"), and the "Arrival of Hernán Cortés in Veracruz".
 These are part of a series depicting the pre-Hispanic era.
 Peoples such as the Tarascos of Michoacán, the Zapotecs and Mixtecs of Oaxaca and the Huastecs of Hidalgo, San Luis Potosí and Veracruz.
