However, the second floor was not finished until 1950 when a total renovation was completed.

The neoclassical facade is made of polished gray quarry stone, giving it an air of simplicity and elegance. In 1960, a replica of the Dolores Bell was installed.

In the Juárez Hall, there is a plaque commemorating the visits made by Benito Juárez to the building in 1863 and 1867.
