In Mexico, mosaics have been utilized as a durable alternative to traditional painted murals, particularly for decorating the exterior walls of buildings where standard mural paints are susceptible to rapid deterioration.12

Following the government-led mural movement of the 1930s and 1940s, which focused on public education through historical and political themes, artists sought more resilient media for outdoor surfaces. Mosaic proved to be a logical solution, offering both longevity and the ability to decorate large, unbroken architectural spaces.1

Many prominent Mexican muralists transitioned to this medium, often designing the mosaics themselves. Notable examples include:

  • Juan O’Gorman: A prolific architect-muralist who created the monumental mosaic on the exterior of the National Autonomous University of Mexico library (1951–53) and decorated his own home with symbols from Aztec mythology.1
  • Diego Rivera: Designed the immense mosaic facade for the Teatro de los Insurgentes in 1953.1
  • Francisco Eppens and Xavier Guerrero: Both utilized historical themes in their mosaic decorations for public institutions and cinemas.1
  • Carlos Mérida: Known for his abstract mosaic designs, such as those created for the Reaseguras Alianza in Mexico City.13
