Duomo di Alghero

Alghero Cathedral, otherwise the Cathedral of St. Mary the Immaculate (Italian: Cattedrale di Santa Maria Immacolata), is a Roman Catholic cathedral in Alghero. It was the seat of the Bishop of Alghero from 1503 to 1986, and since 1986 has been that of the Bishop of Alghero-Bosa. The church was originally in Catalan-Gothic style, as can be seen in the five chapels and ambulatory of the presbytery, which also includes the octagonal base of the bell tower. The nave and the two aisles are however in Late Renaissance style. In the 19th century a Neo-Classical narthex was added to the façade, which dramatically changed its appearance.
