La Hacienda de San Diego de Navacoyán, located on the banks of the Tunal River in the present-day state of Durango, was another significant stop on the itinerary of the Camino Real de Tierra Adentro. Travelers needed to cross this river to continue their route towards Chihuahua and New Mexico.
Antigua hacienda de San Diego de Nanacoyán y Puente del Diablo
Passing through this area was challenging, especially during the rainy season when the current would sweep away anything in its path. Historical records tell us that in 1782, Pedro Minjares, the owner at that time, ordered the construction of a sturdy bridge that could withstand and facilitate constant transit even during the worst rainy seasons. However, popular tradition has perpetuated a fantastic version where it is said that several attempts were made to build the bridge, but success was elusive. Sometimes it was due to the inexperience of those in charge, and other times it was due to the forces of nature.
Given this situation, the owner of the hacienda decided to bring in from Zacatecas a master builder renowned as the best in the entire northern region. Frustrated with losing money, he stipulated in the contract that the work must be completed within a specified timeframe; otherwise, he wouldn't pay a single cent. Confident in his skills, the master builder hired the best team of laborers he could find in the area. Everything seemed to be progressing according to plan, but when the project was more than halfway completed, an unusually strong storm hit. When he conducted the mandatory inspection to assess the extent of the damage, he painfully realized that a significant portion of the work had been lost, making it impossible for him to meet the deadline. That night and the following ones, he couldn't sleep, trying to find a way out. On the evening before the fatal deadline, his desperation led him to shout that he was willing to sell his soul to the devil in order to finish the bridge on time. Suddenly, in the midst of a whirlwind that formed without even the slightest breeze blowing, the figure of a man dressed entirely in black appeared. He told him that he took his word and accepted his soul in exchange for finishing the bridge before the first ray of the new day. The master agreed, and throughout the night, the sound of a strange group moving stones and whispering unintelligibly could be heard.
At dawn, some peasants who were heading to their tasks saw the bridge spanning gracefully across the river. One of them rushed to inform the owner of the hacienda. The master builder was walking across the bridge when he noticed that a stone was missing at one end. Quickly, using some mud, he placed the missing piece back into its place.
At that moment, the hacendado arrived, inspected the bridge thoroughly, and was extremely satisfied, so he paid the agreed amount. As the master was leaving, he passed over the bridge again and noticed that the stone he had placed minutes earlier was missing once more. Suddenly, the shadowy figure of the man in black appeared demanding payment.
Skillfully, the master refused to comply, arguing that the bridge was incomplete because it was missing a stone. Deprived of arguments, the devil had no choice but to disappear in the same way he had arrived.
