Calzada de los Frailes is a picturesque colonial street stretching from the city center to the Convent of San Bernardino. Lined with pastel-colored houses, many have been converted into boutiques, cafes, and art galleries. The cobblestone street dates back to the 16th century when Franciscan friars would walk this path. Today it is one of the most photographed streets in Mexico, especially at sunset when the colorful facades glow warmly.
