Work on the New Cathedral started in 1722 and was supervised by the architect Vicente Acero, who had also built the Granada Cathedral. Acero resigned from the project and was succeeded by several other architects. As a result, this largely Baroque-style cathedral was built over a period of 116 years, and, due to this drawn-out period of construction, the cathedral underwent several major changes to its original design. Though the cathedral was originally intended to be a baroque edifice with some rococo elements, it was completed in the neoclassical style. Its chapels have many paintings and relics from the old cathedral in Cadiz and as well as from monasteries throughout Spain.
