The church was originally built in 1176 by the Normans under the reign of William II.
It holds several marble statues by Antonello Gagini, a renowned 16th-century sculptor from Sicily.
The church became a co-cathedral of the Diocese of Mazara del Vallo in 1967.
Much of the current architectural character resulted from extensive reconstructions following the 16th and 17th centuries.
The interior preserves a wooden crucifix dating back to the 15th century.
The Chiesa Madre of Marsala, dedicated to Saint Thomas of Canterbury, stands as the primary religious site in the city center. Originally constructed on the site of a Norman church, the current structure dates back primarily to the 16th and 17th centuries. The facade features a distinct Baroque style completed in the 18th century. Inside, the church houses significant artistic works, including marble sculptures attributed to the Gagini school. The interior layout follows a Latin cross plan with three naves divided by granite columns. It serves as the co-cathedral of the Diocese of Mazara del Vallo. The building is centrally positioned within the Piazza della Repubblica, historically the focal point of civic life in Marsala.
