Alghero Cathedral

Alghero Cathedral, otherwise the Cathedral of St. Mary the Immaculate (Italian: Duomo di Alghero; Cattedrale di Santa Maria Immacolata Catalan: Catedral de l'Alguer; Catedral de Santa Maria Immaculada), is a Roman Catholic cathedral in Alghero in the province of Sassari, Sardinia, Italy.

Alghero was designated as a diocesan seat in 1503 but construction work on the cathedral did not begin until 1567.

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 main altar was designed by the Genovese artist Giuseppe Massetti (1727): the sculpture shows Mary the Immaculate flanked by angels.

The cathedral is the burial site of the Italian-born Duke of Montferrat (1762-1799) and his brother Count of Asti (1766-1802) who died on the island having caught malaria.
