The Toluca Cathedral is a Catholic temple built on the site of the Franciscan convent of the Assumption of Mary, constructed in the 16th century. 

The cornerstone was laid in 1867, and its construction was slow, taking 111 years and going through several stages.

The architect who completed the Cathedral in its final period from 1951 to 1978 was Vicente Mendiola, who also had other important constructions in different parts of the country, such as the design of the Diana the Huntress Fountain in Mexico City, the Municipal Palace of Guadalajara, and the Customs House of Tampico.

The patron saint of the city of Toluca, Saint Joseph, is venerated in the cathedral.

Its architecture is neoclassical in style. The facade consists of two levels, where the images of Saint John, Saint Thomas, Saint Peter, and Saint James are located. The relief representing the Ascension of the Lord, made of mortar, is particularly noteworthy and is located on the pediment of the facade.

At the top of the pediment, there is a clock and three female figures representing the theological virtues: faith, charity, and hope.

The Cathedral is composed of a nave located parallel to the facade, a central nave, and two side aisles. 

The southeastern column that supports the dome covering the main altar has a staircase inside, which leads to the balconies inside the dome. At the top of the dome, there is a large six-meter statue representing Saint Joseph with the baby Jesus.

Inside, it has a unique feature as it houses the facade of another church, the San Elzeario or Third Order Church, currently known as the Sagrario Parish.
