The Basilica of Our Lady of Guadalupe
Mexico City's great Marian shrine and the most visited Catholic sanctuary in the Americas
Catholic tradition holds that in December 1531, on the hill of Tepeyac north of the ruined Aztec capital, the Virgin Mary appeared to Juan Diego Cuauhtlatoatzin, an Indigenous convert, speaking to him in Nahuatl. As a sign for the bishop, she is said to have left her image imprinted on his cloak, the tilma. That image, a dark-skinned Mary standing on a crescent moon, has become the most powerful religious symbol in Mexico and far beyond. The shrine built around it on the edge of Mexico City is the most visited Catholic sanctuary in the Americas. On her feast day, December 12, millions converge on foot, by bicycle, and by bus, many having walked for days.
The shrine complex lies at the foot of Tepeyac Hill in the Gustavo A. Madero borough of northern Mexico City. Its focus is the modern basilica of 1976, designed by Pedro Ramírez Vázquez, a vast circular church under a sweeping tent-like copper roof, built so that all its roughly 10,000 occupants can see the tilma, which hangs above the main altar. Moving walkways beneath it carry visitors past for a close view. Beside it stands the old basilica, completed in 1709, a baroque church that sank unevenly into the soft lakebed soil and was closed for decades of stabilization. Chapels climb the hill above, including the Capilla del Pocito, with its tiled domes, and a hilltop chapel marking the place of the apparitions.
A chapel stood at Tepeyac by the 1530s, and devotion grew through the colonial period. Mary of Guadalupe became a national emblem: Miguel Hidalgo carried her banner when he launched Mexico's independence struggle in 1810, and popes later named her patroness of the Americas. Pope John Paul II canonized Juan Diego at the basilica in 2002. Estimates of annual visitors commonly run to about 20 million, and Mexico City authorities counted about 12.8 million pilgrims on December 11 and 12, 2025, a record. The crowds require large security operations, while the old basilica's subsidence and the condition of the centuries-old tilma, kept behind protective glass, are long-term conservation concerns.
