Its construction lasted between 1747 and 1816. It is made of carved stone and is a solid masonry work. It was elevated to a minor Basilica by Pope Pius IX on November 20 of the same year. Later, the Atlantes were added between the towers and the central part. Since then, the city of León has the privilege of possessing The largest cathedral in Central America and one of the most beautiful in America.

It is a unique architectural relic on the American continent, it has its own light, given its impeccable interior and the ingenious arrangement of its skylights, oriented to follow the movement of the sun in sequence throughout the day, it has 5 naves, 3 floors and 3 architectural styles (colonial, baroque and neoclassical). On June 28, 2011, it was elevated by the UNESCO a Heritage. Popularly known as Leon Cathedral.

In 1680, under the impetus of the Bishop Andres de las Navas and Quevedo, was erected in Leon on Tridentino San Ramón School, which was destroyed by an earthquake. In 1752, under the direction of the field master Francisco Benítez de Salamanca, the new building was erected.

The importance of the seminary was confirmed in 1812, when the Cortes of Cádiz granted it the privilege of university seat, and the University of León was founded. Finally, the university abandoned the building to become a seminary again until 1945. The facade is symmetrical with Renaissance and neoclassical influences. in perfect balance achieved by highlighting the interior modulation through cornices and chains, arranging in vain in each of the frames; doors on both levels and balconies with overhangs on the upper levels. Today it remains a Catholic School.

Built in 1679 by Bishop Andres de las Navas and Quevedo, being used as Episcopal palace. The school maintains its main façade with a complex style, with elliptical characters predominating over neoclassical ones, combining the eastern façades with a sober and traditional line, with the courtyard and corridors on two floors. The chapel has a neo-Gothic façade, symmetrical and divided into 3 bodies with 5 streets, finished with a crowning gable and spires. The stained glass windows stand out, mainly those of the rose window of the main façade, which is currently part of the Assumption Catholic School.

The old church of La Merced was built at the same time as the convent of the same name, approximately in the year 1762 by the Mercedarian Friars, the only church that has its bell tower outside the line of the facade, on an interior plane, which suggests that it was built later, baroque, without the purity of the Recollection Church, combining the influences of these styles such as neoclassical on the main facade and colonial on its south side, this temple holds one of the oldest Images from the time of the Conquest, such as the venerated Image of the Virgin of Mercy, Patron Saint of the City of León.

The original temple was founded in 1639 by Friar Pedro de Zúñiga. In 1830, when the religious order was expelled from the country, the church underwent many alterations, with very few of its original elements remaining. At the beginning of the 60s, the main façade was destroyed to make way for the one we see today. In 1985, its altars were restored. The sacristy space is well carved and decorated, especially in the beams and braces. The church has a gabled roof, which is cut off at the presbytery, which has an independent roof.

La first stone was placed December 5th 1786, by Bishop Juan Félix de Villegas. It was founded by the Recollect Fathers of the congregation of San Francisco de Nery. Next to the church, the Recollection school was built, established on November 22, 1880 by Sister Victoria Antonieta Holfembeiem, of French nationality, belonging to the congregation of the Brothers of Saint Vincent de Paul.

It is a baroque monument par excellence, its façade is considered the most important in León, as it is the unique carved in stone, whose gable corresponds to the Mexican baroque that unites admirably and harmoniously with the tower through the decoration of religious symbols. It is notable neoclassical influence in the interior decoration, mainly in the supporting elements.

The church forms a visual culmination of Calle Real, breaking with the visual axes of the city and constitutes, with the Laborío complex, one of the most interesting urban landmarks due to its spatial distribution. Built in the first half of the 18th century, its structure corresponds to one of the many typological solutions developed by colonial religious architecture. The plastic composition of the façade is predominantly neoclassical, a product of the growing French influence in Spain.

It has an altarpiece flanked by two towers at the same height. It has two bodies that maintain continuity through an entablature with architrave, friezes and cornices very well defined.
