Alghero was built by the Doria of Genoa in 1102. In 1106 John, Bishop of Alghero, assisted at the consecration of the Church of the Trinity in Saccargia.
In 1986 the historic Diocese of Alghero was renamed as the Diocese of Alghero–Bosa preserving the title of the diocese of Bosa while absorbing its territory. Alghero Cathedral remains the seat of the diocese, while Bosa Cathedral is now a co-cathedral.[2]
Other major churches in the diocese are the Basilica of Our Lady of the Snows (Santa Maria della Neve) at Cuglieri, and the Sanctuary of Our Lady of Valverde near Alghero.
