San Luis de la Paz, and its surrounding municipality of the same name, is a city located in the northeastern part of the state of Guanajuato in Mexico. A charming city with great historic and cultural wealth, was founded on August 25, 1552, as a defensive town on the Spanish Silver Road, which linked the Zacatecas mines with Mexico City during the Spanish domination. It owes its name to the peace treaty between Otomi Indians, who were Spaniard allies, and the native Chichimecas, on the day of Saint Louis of France, August 25. The Chichimeca Nation, as it is also known, is an attractive tourist centre.
