Cathedral Basilica of Our Lady of the Light, León, Neoclassical cathedral in León, Guanajuato, Mexico

The Cathedral Basilica of Our Lady of the Light has a cantera-stone facade with two tiers of Corinthian columns framing the round-arched entrance and choir window, topped by a broken pediment with a medallion of two angels holding the Virgin's monogram. Its twin towers rise 70 m in three identical tiers, the east one finished in 1876 and its pair in 1878. Inside, a single 72 m nave with a 13 m width leads to a Carrara-marble altar under a 42 m dome by Manuel Gómez Ibarra.

Construction of the Temple of the New Company began in 1732, when the Jesuits returned to León; after their expulsion in 1767 the walls stood only 8 metres high. The Obregón family resumed work in the 1830s, the vaults were finished in 1833-1837, and the Diocese of León was created on 21 February 1864. Bishop José María de Jesús Diez de Sollano then had the temple completed and consecrated on 17 March 1866; it became a basilica on 5 August 1920.

This cathedral is the religious heart of León and shapes how the city defines itself. People gather daily for services, and during weddings, baptisms, or local celebrations, the interior fills with residents and visitors paying their respects.

The cathedral faces the historic centre, with a small atrium enclosed by a low stone wall and iron railing, entered through three stone portals; a statue of John Paul II stands on the left side. The interior is a single 72 m nave with side chapels, including San José to the east and the Virgen de la Soledad to the west. The two 70 m towers are identical in construction.

The 4.5-tonne main bell was cast in December 1865 and January 1866, just before the cathedral's consecration on 17 March 1866, which took place while the building was still unfinished. The two identical towers, 70 m high, were completed in 1876 (east) and 1878.
