Palacio Legislativo de San Lázaro, Parliament building in Mexico City, Mexico

The Palacio Legislativo de San Lázaro is the seat of Mexico's Chamber of Deputies, built on the grounds of the former San Lázaro railway station. Its main facade on Congreso de Unión Avenue has three sections: red tezontle at both ends and white marble in the center, forming an access plaza. Above the main door, José Chávez Morado's green oxidized bronze bas-relief shows the national coat of arms, flags, a feathered serpent and a sun inscribed with the Constitution.

The building opened in 1981 after the political reform of 1977 increased the number of deputies from 186 to 400 and required larger facilities. The expansion reflected the democratic opening that allowed more political parties to participate in the legislative process.

The session hall displays murals by Adolfo Mexiac showing different constitutions of the country. The artworks offer visitors a visual overview of important legal milestones in Mexican history.

Guided visits offer access to public galleries where debates can be observed. Those exploring the parliament should plan enough time and prepare for security checks at the entrance.

The building's bronze relief above the main door, by José Chávez Morado, combines red tezontle, white marble and green oxidized bronze to reproduce the three colors of the Mexican flag. Its central motif is the national coat of arms, surrounded by flags in motion and a feathered serpent.
