The 'Tree of Thorns' (Mimosa aculeaticarpa) inside the complex reportedly produces thorns shaped like small crosses.
The cross associated with the site is said to have been visible in the sky during the battle between Spanish-led forces and the Chichimeca people in 1531.
Emperor Maximilian I was imprisoned in a cell here after the Siege of Querétaro.
The complex was the starting point for Franciscan missions that established many settlements throughout Northern Mexico and the Southwestern United States.
The convent's hydraulic system includes historical 'arches' that once brought water into the city.
The site was officially established as a mission center in the late 17th century by Fray Antonio Margil de Jesús.
The Santuario y Convento de la Santa Cruz de los Milagros is a historic Franciscan complex founded in 1683. It is most famous for housing a tree with thorn-shaped spines, which pilgrims and locals believe miraculously appeared after a cross was planted on the site in 1531. The convent served as the headquarters for the propagation of the faith in Northern New Spain. It played a significant strategic role in the Mexican War of Independence, serving as the final stronghold for Emperor Maximilian I of Mexico before his surrender in 1867. The architecture reflects the transition from late Baroque to Neoclassical styles. The site contains original colonial-era cells and extensive courtyards. It remains an active religious site managed by Franciscan friars.
