Historical centre of San Luis Potosí City, Historic district in San Luis Potosí, Mexico.

The Historical centre of San Luis Potosí is an old town district in Mexico featuring more than 40 religious and civil buildings from multiple periods. The streets are marked by ornate stone carvings, decorated facades, and interior courtyards that reflect Spanish colonial design traditions.

San Luis Potosí was founded in 1592 after gold and silver were discovered at Cerro de San Pedro, by captain Caldera, Juan de Oñate and viceroy Luis de Velasco y Castilla. City status was granted in 1656 by viceroy Francisco Fernández de la Cueva and confirmed by King Philip IV two years later. The historic centre was decreed a national monument zone by President Miguel de la Madrid on 14 November 1990, published in the Diario Oficial on 19 December 1990, and in 2010 UNESCO listed it within the Camino Real de Tierra Adentro World Heritage Site.

The streets show how locals and visitors naturally use the plazas and colonial buildings as gathering spaces throughout the day. Religious processions and public events take place in these settings, making them active centers of everyday community life.

Access to the district is straightforward and guided walking tours are organized daily from the tourist information office. It helps to wear comfortable shoes since the streets are made of stone and can become hot under the sun.

The buildings are made from pink quarry stone sourced from local mines, and this stone shifts color depending on where the sun is in the sky. This creates a fascinating effect where the same structures display different hues throughout the day.
