Dolianova Cathedral, Co-cathedral in Dolianova, Sardinia, Italy

Dolianova Cathedral is built of sandstone in a Pisan-Romanesque style with Gothic elements from its last construction phase at the end of the 13th century. Its façade, sides, apse and bell tower carry pilasters and Lombard bands with sculpted geometric patterns, human figures and mythological animals. Inside, a nave and two aisles are divided by cruciform pilasters, some of the Gothic polycolumn type.

Construction began in the 12th century and continued into the 13th, with the building later becoming the seat of a diocese. In the early 1500s, it lost this episcopal status, marking a shift in its religious importance.

The sculpted capitals of the interior depict New Testament scenes, among them the Nativity and the Adoration of the Magi. The church is dedicated to Saint Pantaleon, and the diocese of Dolia, of which it was the seat, is documented from 1089 to 1503, when it was merged into the Archdiocese of Cagliari.

The cathedral stands in the historic centre of Dolianova, on a small square reached through an arch off Via Vescovado. The Palaeo-Christian baptismal font is kept under the presbytery, and the carved capitals of the nave and aisles are at eye level along the columns. The north side, beside the main entrance, holds a niche with two columns supporting a Roman sarcophagus.

The Palaeo-Christian baptismal font kept under the presbytery is the oldest surviving trace of worship here, older than the 12th-century church itself. The diocese of Dolia is documented from 1089 to 1503, when it was merged into the Archdiocese of Cagliari.
