Catedral Santa María de la Asunción de Ceuta (or St. Mary of the Assumption), the city’s main cathedral, was built on the site of a mosque converted to a place of Christian worship in the 15th century, after the Portuguese conquest. That initial cathedral was declared a ruin in the 17th century, and was rebuilt and much altered over the years, with a final restoration in the 1720s. Architecturally it resembles the Cathedral of Cádiz on mainland Spain. The adjacent museum has a collection rich in Baroque-period art and sculpture.
