Bosa Cathedral, dedicated to the Immaculate Conception (Italian: Duomo di Bosa, Concattedrale dell'Immacolata Concezione), is a Roman Catholic cathedral in Bosa, Sardinia, Italy. It is a co-cathedral of the Diocese of Alghero-Bosa; before the creation of the merged diocese in 1986 it was the seat of the Bishop of Bosa.
The cathedral stands in the historical town centre of Bosa, between the Corso Vittorio Emanuele II and the River Temo, at the height of the 19th-century bridge.
The origins of the cathedral lie in the 12th century, but the building has been substantially altered many times, particularly during the 15th century. The present building is the product of restorations carried out from 1803 onwards by the local architect Salvatore Are. The cathedral was re-consecrated in 1809. The decorations and furnishings were completed during the rest of the 19th century.
Externally the building is characterized by two cupolas covered in tiles of coloured majolica, and by the squat bell tower in red sandstone, uncompleted, carved with the date 1683. The same stone also characterizes other parts of the building, including the Rococo decorations of the façade with its distinctive lesene (applied stone strips or false pilasters) and cornices.
