Cattedrale di Santa Maria Immacolata (Cathedral of Saint Virgin Mary), Alghero (must see)

The Cathedral of Saint Virgin Mary is a significant Roman Catholic cathedral. Serving as the episcopal seat since 1503, the cathedral's long and complex construction reflects its historical and architectural evolution. The site was designated as a diocesan seat in 1503, but actual construction did not commence until the 1530s. It took over 60 years to open, and the cathedral was not fully completed and consecrated until 1730.

Originally built in a Catalan-Gothic style, the cathedral features several architectural elements from this period, including the five chapels and ambulatory of the presbytery, as well as the octagonal base of the bell tower. However, the nave and the two aisles were constructed in the Late Renaissance style, showing a transition in architectural trends during the cathedral's lengthy building process. This blend of styles adds to the building's historical richness and visual interest.

In the 19th century, a Neo-Classical narthex was added to the cathedral’s facade, dramatically altering its appearance and adding a new layer of architectural complexity. The cathedral also serves as a burial site for notable figures, including the Italian Duke of Montferrat and his brother, who died on the island of malaria in the late 18th century.

Today, the Cathedral of Saint Virgin Mary stands not only as a place of worship but also as a monument to the diverse architectural styles and historical phases that have shaped Alghero.
