the Supreme Court. During an uprising led by Valentín Gómez Farías against then-president Anastasio Bustamante, the southwest balustrade was seriously damaged during a siege lasting twelve days. In 1845, the old Chambers of Deputies was constructed, with the Senate on the upper floor of the south wing. In 1850, Mariano Arista had the old north prison door cemented shut and constructed the current northern door. He also converted the north wing into barracks of the "Batallón de Guardia de Supremos Poderes" (Battalion of Guards for the Supreme Powers). In 1864, Maximilian of Habsburg had three flagpoles installed in front of the three main doors. By the central door was the Mexican flag; at the north door was the flag of Austria and at the south door was the flag of France. He also had Lorenzo de la Hidalga construct the grand marble staircase that is in the Patio of Honor in the southern wing, as well as having the public rooms roofed and furnished with paintings, candelabras, and chamber pots from Hollenbach, Austria and Sirres, France. In opposition, Benito Juárez chose to have his quarters in the north end of the Palace, rather than in the traditional southern end. In 1877, the Secretaría de Hacienda y Credito Público (Secretary of Internal Revenue and Public Credit), José Ives Limantour, as part of his overhaul of the department, moved their offices to the north wing, finishing in 1902. He chose the largest room in the wing for the Office of Seals. In 1896, the bell that Father Hidalgo rung at the parish of Dolores, Guanajuato was moved here. A number of changes were made during the rule of Porfirio Díaz. The English-made clock on the parapet was moved to the tower of the Church of Santo Domingo. The façade was cemented over and etched to look like stone block. Cloth awnings were placed on the windows of the upper floors. On pedestals near the main door, statues of female forms were placed. Inside, the ambassador's room, the dining room, the kitchens, the lounge, the garages and the stables were all refurnished. This was done at a time when French style was popular in Mexico. Between 1926 and 1929, the third floor was added during the term of President Plutarco Elías Calles by Alberto J. Pani, an engineer and then finance minister and designed by Augusto Petriccioli. Merlons were placed on the towers
