TheMexico City administrative buildings are two buildings on the south side of theZócalo inMexico City divided by the avenueAvenida 20 de Noviembre. They house offices of the governing authority of Mexico City. The building to the west of20 de Noviembre is the older one and has been the site of city administration since theConquest. The one to the east is newer, built in the 20th century.[1]
Similar to other capital cities, likeWashington, D.C., Mexico City is considered as belonging to the nation, rather than being part of a particular state. What is now the federal district used to be principally part of theState of Mexico until 1824, when the Mexican Congress decided to put the capital in Mexico City. At the time, the State of Mexico had its headquarters in the old Palace of the Inquisition (Now the Museum of Medicine) but then had to move toTexcoco. The government of Mexico City and the Federal District are one and the same, causing Mexicans to use the terms interchangeably. While it is still considered under federal jurisdiction, recently, changes have been made, such as the allowing of direct elections of the Chief or "mayor" of the District.[2]


The first local authority inNew Spain was theayuntamiento (district council) ofVilla Rica inVeracruz, established whereHernán Cortés came ashore in the early 16th century. The governing council moved toCoyoacán, near Mexico City, after the fall of the Aztec cityTenochtitlan. The ayuntamiento moved here after the first town hall was built between 1526 and 1532,[1] with the first recorded council meeting here in 1526.[3] It was built as a fortress against the Indians, who were forbidden to settle in the area. It had a large meeting room, ascrivener's room to keep records, another for accounting, and audience hall, a chapel and asacristy.[4] This building also housed a government-controlled butchers and granary[5] Since then, the governing body and building have gone by several names including the "Casas Consistoriales", the "Casas de Cabildos", the "Palacio de la Diputación", the "Sala de Cabildos" and the "Consejo Consultivo de la Ciudad." The building was expanded in 1582.[2]
In 1582, a jail was added, the first such in New Spain.[1] Other functions were added to the building such as a coin-making facility, a foundry and residences.[4] This building was destroyed, along with theNational Palace in the famine uprising in 1692 .[1] As the building burned, its archives were saved by Carlos de Sigüenza who, with the help of friends and paid servants threw them out of the windows as the building burned, saving records going back to 1524[5] In 1714, viceroyFernando de Alencastre, 1st Duke of Linares ordered the building reconstructed. Work began in 1720 under viceroyBaltasar de Zúñiga, 1st Duke of Arión, who managed to have the portals built. The rest of the building was completed in 1724 under viceroyJuan de Acuña, marqués de Casafuerte. The official corn and meat markets located here were abolished and the free market was allowed to take control of these commodities. This resulted in a bustling market in what was the Alley of the Diputación, now 20 de Noviembre. However, these stalls disappeared by 1888.[2]
In 1910, the building was remodeled for the upcoming centennial ofIndependence by architectManuel Gorozope[1] and engineer Guillermo Beltrán. The remodeled building was inaugurated on 16 September (independence day) 1910. However, remodeling work went on from 1912 to 1930 with the addition of the main staircase, the library and the archives, even though work was periodically halted because of theMexican Revolution.[2] In 1921, another floor was added as well as square towers on the corners on both sides of the main facade. This front facade hastalavera tile murals with thecoats of arms of Coyoacán, where the ayuntamiento was before here, of the founding of Mexico City, ofChristopher Columbus, of Hernán Cortés, of Mexico City as authorized byCharles V and of Villa Rica de la Vera Cruz.[1] In some places, some of the foundations of the original building can still be seen.[4] In 1948, the district council moved from here to the new building built next door, but it moved back here in 1997.[3]
The exterior of the building is topped by two square corner towers, each containing three small arches, whosebalustrade appears to spill over thepediments and the eagles that overlook the Zocalo.[6]
The interior has large powerful arches, with richly decoratedmoulding at the main entrance. These lead to a double arcade covering a monumental staircase created by architect Alvaro Aburto. On each side of the stairwell are two patios surrounded by arches and columns. The left patio is done in Venetian-style mosaics with images fruits and vegetables as well as large pitchers.[6] The right side patio is home to the Salon de Cabildos, which was recently restored and open for public viewing. It was the place that the city council traditionally convened to settle local disputes. The entry hall to the Salon contains a gallery of portraits of all 62 Spanish viceroys.[7]

This building is next to the National Palace and theSupreme Court building. After demolition of the old colonial-period Portal de las Flores in 1935,[6] the current structure was built between 1941 and 1948[1] and designed to fit in with the rest of the architecture of the Zocalo,[2] as well as to be symmetrical with the "old" Palace of the Ayuntamiento next door.[6] The Portal de las Flores (Portal of the Flowers), named so either because its original owner's name was Flores, but since later it housed markets selling fresh flowers, vegetables and fruit from outlying areas, it is commonly held as the origin of the name[5] This Portal was rebuilt in 1724 and remained the site of markets and stores until the 19th century. The 18th-century building was demolished in 1935, helping to open up 20 de Noviembre Street and clearing way for the current building.[1]

The outside of the building has relatively sober decoration with windows framed in white stone,parapets with windows and square columns. The "mini-balconies" of the windows are done inwrought iron and the corners of the third floor have estipite columns.[6] In 1985 this building suffered damages due to theMexico City earthquake and was remodeled and restructured. A plaque inside the building commemorate that works.
The interior of thevestibule is simple dominated by the main stairwell. This stairwell contains two large murals depicted thehistory of Mexico from the pre-Hispanic period to just past theRevolution. Both were painted byCarlos Montuy in 1986 .[6]
When the current edifice was being built, they found the remains of the house of Doña Marina orLa Malinche and that of the wife of treasurerAlonso de Estrada. Further down, they found a "tlachtli" or Aztec ball game field, achacmool and other archeological finds.[2][5]
A number of Federal District department or secretariats are housed in the two buildings. In the original building are housed the "Jefatura de Gobierno" (offices of the Chief of the District), theSecretaría de Gobierno (Secretariat of the Government), and the "Secretaría de Medio Ambiente" (Secretariat of the Environment). In the newer building are housed the "Oficialia Mayor" (Government Oversight), theSecretaría de Desarrollo Social (Secretariat of Social Development), theSecretaría de Obras y Servicios (Secretariat of Works and Services) and theSecretaría de Protección Civil (Secretariat of Civil Protection).[8]
The Chief of the Federal District since 2018 isClaudia Sheinbaum. While the Old Town Hall is overshadowed by the National Palace andMexico City Cathedral, it has been the scene of some political and social events. In December 2007, microbus operators protested there for a number of days until District ChiefMarcelo Ebrard promised to meet with them about their demands for higher tariffs.[9] In the same year, the city sponsored a light show projected onto the side of the building, representing different eras in Mexico City's history. It was called "Mexico DF: una historia en luz" (Mexico, Federal District: a history in light). The show included images and music.[10] President of SpainJosé Luis Rodríguez Zapatero visited the old Palace in 2007 as well, praising Mexico City as the vanguard of social change for the country as he was given the keys to the city.[11]
