The Curse of Don Roque — Unearth the Mine's Dark Secret

Your quest begins in the Plaza de Armas, Zacatecas' administrative and social heart since the 16th century. This main square, approximately 100m x 80m, is Spanish-paved and surrounded by covered porticos, typical of Mexican colonial architecture. Facing you stand the Basílica Cathedral and the Palacio del Gobierno, forming the city's major monumental complex. Here, you examine the first clues, enigmatic engravings seemingly linked to the city's founders, notably Juan de Tolosa, discoverer of silver deposits in 1546. The city's motto, "Zacatecas, Patrimonio de la Humanidad," resonates with the historical significance of the site.

The Basílica Cathedral of Zacatecas, construction begun in 1729 and completed in 1752, is your second stop. Its facade of local pink stone, approximately 35 meters high, is an example of the Churrigueresque style. The two symmetrical side towers rise to 40 meters. Inside, you study the gilded 18th-century altarpieces and works by Miguel Cabrera, a renowned Baroque painter, which might conceal messages. This monument, declared a UNESCO World Heritage site in 1993, was the spiritual center of the mining city, where miners sought comfort and protection from the dangers underground.

Continue to the Palacio de la Mala Noche, an 18th-century colonial building. This former stately home, with its civil Baroque architecture and carved stone facade, is intimately linked to mining. Its traditional name, 'Palacio de la Mala Noche' (Palace of the Bad Night), refers to local legends and the misfortunes of miners. Here, you discover encrypted documents, perhaps silver production records or gallery maps. The inner courtyard with its arcades provides a setting to decipher clues, connecting the palace's mysteries to the depths of Zacatecas' historic mines.

Your investigation then leads you to the Acueducto El Cubo, a critical infrastructure built in the 16th-17th centuries to supply Zacatecas with water from mountain springs. Its limestone arches, extending about 4 kilometers with a maximum height of 20 meters, were crucial for the development of mining and urban supply. The Teleférico de Zacatecas, inaugurated in 1973, connects the city center to the Cerro de la Bufa, offering panoramic views of the historic mines and the valley. From the top of Cerro de la Bufa, at 2,650 meters, you observe the extent of the mining city and the marks left by centuries of silver extraction, preparing for the final phase of your investigation.

Your journey brings you back towards the Ex Convento de San Francisco, a Franciscan foundation from the 16th century (circa 1550). Its two-story cloister and adjoining church with a Baroque altarpiece served as an evangelization center for the mining populations. It is here, in this place of contemplation, that you gather the last pieces of the puzzle before heading to Mina El Edén. This silver mine, exploited since the 16th century and reaching 600 meters deep, was the foundation of Zacatecas' colonial wealth. Now an underground museum, its historic galleries and mineralogical exhibition will finally reveal the truth about Don Roque's curse. You will have explored the Mexican colonial heritage and the history of Zacatecas, a UNESCO World Heritage city since 1993, through a thematic circuit of the Bajío.
