San Luis Potosi, as a member of LUCI (Lighting Urban Community International), and the World Association of Cities of Light, is the first city in Latin America to hold a Festival of Light. In Europe, a similar festival is held from December 5 to 8 in the City of Lyon, France.
As part of the celebrations for being the only Latin American city to be part of the global illumination program, San Luis Potosi hosted in December 2007, March and November 2008, two major Festivals of Light.  The first was displayed at El Carmen Church, and the second at the Metropolitan Cathedral, in both cases bringing thousands of visitors attracted by the flashing colors of the dazzling spectacle.
The next edition of the Winter Light Festival 2008 called “A Wall of Light in San Luis Potosi” was held from December 13, 2008 to January 6, 2009 in the Founders Plaza (illuminating the Central Building of the University, The Loretto Chapel, and the Church of the Company), in the historical heart of the city.

The work of French painter and stage designer Xavier de Richemont, this show is done through countless sets of lasers, lights, prisms, photographs, images and world class technology, which include elements of history and San Luis culture, and illuminate the facades of these buildings.
