Cathedral Basilica of Our Lady of the Rosary, Neoclassical cathedral in Culiacán, Mexico.

The Cathedral Basilica of Our Lady of the Rosary is a Catholic church in Culiacán whose construction began on 22 May 1842 and was completed in 1885. Its architectural language is predominantly neoclassical, with some 19th-century eclectic elements. It is the seat of the diocese of Culiacán, though the churches of Tabalá and Tacuichamona, from the 18th century, are older.

Construction began on 22 May 1842 under Lázaro de la Garza y Ballesteros, seventh bishop of Sonora. Work stopped, was restarted in 1855 by Pedro Loza y Pardavé, then halted again during the Reform Movement. José de Jesús Uriarte finally completed the building in 1885. The older churches of Tabalá and Tacuichamona, from the 18th century, predate it in the municipality.

The cathedral is dedicated to Our Lady of the Rosary and serves as the seat of the Diocese of Culiacán. It is not the oldest church in the municipality: the churches of Tabalá and Tacuichamona date from the 18th century, older than this 1842 building.

You can visit the cathedral during the day by entering through the main entrance facing the plaza. Keep in mind that hours may be extended during religious festivals and special celebrations, so it helps to ask locals about upcoming events.
