On north annex of the building is the Treasury Room and the Benito Juárez Museum. Between the two is the Empress Stairway, built by brothers Juan and Ramón Agea. When faced with claims that their work was unstable and would collapse, they had a full battalion charge down them while they stood underneath. The Treasury Room is no longer in use. Leading to the Museum part of the complex, which used to be the Finance Ministry, is a statue of Benito Juárez by Miguel Noreña. This work was criticized at the time because it was felt that such an honored person should not be depicted sitting on his coattails, as it was contrary to social etiquette at the time. In the Finance Ministry patio is the Benito Juárez Room, where this president lived during the end of his term and where he died on July 18, 1872. The bedroom, living room and study have been preserved complete with a number of objects belonging to the president.
