The Story of Two Aqueducts
The Aqueducts of
Guanajuato
Arches of Adaptation
Long before Guanajuato dazzled with its colonial facades and underground roadways, it was a city shaped by water—or the lack of it. The aqueduct, often overlooked by hurried tourists, is a quiet monument to ingenuity, resilience, and the heartbeat of a mining town that refused to dry up.
​
Engineering & Purpose
​
Built in the 18th century to channel water from the surrounding Sierra de Guanajuato, the aqueduct was more than a feat of engineering—it was a lifeline. Its graceful arches carried water to fountains, homes, and silver-processing mills, sustaining the booming mining economy and the families who depended on it.
​
Crisis and Adaptation
​​
But the aqueduct also tells a story of adaptation. As the mines expanded and the city grew, flooding became a threat. The very water that once gave life began to endanger it. In response, Guanajuato’s engineers rerouted the river underground, transforming the aqueduct from a vital artery into a historical relic.
Today, its arches still stand—some hidden behind buildings, others proudly framing plazas. They whisper of a time when water was wealth, and stone was strategy
A Monument of Love,
​
Stretching across the skyline of Querétaro with 74 majestic stone arches, the aqueduct is one of Mexico’s most iconic colonial landmarks. Built between 1726 and 1738, it spans 1,280 meters (4,200 feet) and reaches a height of up to 28.5 meters (94 feet) Though no longer used to carry water, it remains a symbol of the city’s ingenuity, elegance, and enduring spirit

Why It Was Built
​
In the early 18th century, Querétaro was flourishing—but lacked clean drinking water. The city’s old canals were contaminated, and the Capuchin nuns, who played a vital role in community care, petitioned for a better solution. Enter Don Juan Antonio de Urrutia y Arana, the Marquis of Villa del Villar del Águila, who took on the challenge—not just out of civic duty, but, legend says, out of love for one of the nuns.

Engineering Marvel
​
Inspired by Roman aqueducts in Segovia, Mérida, and Tarragona, the Marquis commissioned a gravity-fed system to carry water from the Ojo de Agua del Capulín spring in La Cañada to the city center. The aqueduct’s open channel was built atop semicircular arches using elemental tools—levers, lead weights, and rudimentary surveying equipment. Despite its simplicity, the design was masterful: it delivered up to 30 liters per second of clean water to Querétaro’s fountains
