The first documents about Dolia date to 1089, when the bishop Virgilio signed the act of foundation of the monasteries of Saints Giorgio and Genesio, created by the will of Arzone, judge of Cagliari.

In 1503 the diocese of Dolia was united with the diocese of Cagliari.

At the end of the era of Giudicati, San Pantaleo and Sicci followed different roads: the first one became a fief of Suelli's bishop. Then, the archbishops of Cagliari, become barons, made San Pantaleo the most important centre of the zone, which exercised its power on the villages of Donori, Serdiana, Sicci, Soleminis, and Ussana.

The small village of Sicci San Biagio, during the Aragonese domination, was transformed into a baronage and assigned to Raimondo De Amburra. Sicci thenceforth became a fief of the dukes of Mandas y Tellez Giròn de Alcantara, who maintained it until the end of feudalism. In 1846 San Pantaleo had 1360 inhabitants, Sicci 727.

The two ancient villages of San Pantaleo and Sicci San Biagio, once separated by the great gardens of the villa of Marchioness Boyl of Putifigari (which is now the museum of oil “Sa Mola de su Notariu”), are the two quarters of the modern Dolianova.

Ecclesiastical history edit

Under the name Dolia, Dolianova was the seat of a diocese.^[2] It was set up around the year 1100; the date 1112 is given, but Benedetto of Dolia was bishop from around 1095,^[3] and 1112 is the year of his death. The earlier date 1089, for bishop Virgilio, is attested.^[4]

The diocese was suppressed in 1503, its territory going to the diocese of Cagliari.^[5][6]

It was revived as a Catholic titular see in 1969. Kevin M. Birmingham was appointed titular bishop in 2020 and remained him until his death.
