Under Porfirio Díaz, Mexico commissioned a Federal Legislative Palace from the French architect Émile Bénard. According to Excélsior, “la construcción fue suspendida en 1912 dejando abandonada su estructura metálica” (construction was suspended in 1912, leaving its steel frame abandoned). From 1933, the architect Carlos Obregón Santacilia used part of that structure to build the Monumento a la Revolución. The monument was completed in 1938. (Video in Spanish.)
