The construction of the current Legislative Palace is a consequence of the political reform of 1977, which increased the number of deputies from 186 to 400, making it impossible to place them in the then former building known as “The Donceles Legislative Palace”.

This motivated the construction of a new location, as part of an urban regeneration plan for the area where the San Lázaro railway station and shunting yards were located.

It was formally inaugurated on September 1, 1981, on the occasion of the President López Portillo 5th Government Report.

The place known as “Palacio de San Lázaro”, in addition to being a monumental building with art and murals of great value in its interior, is full of history that has given way to our country.
