Sant'Adoeno, Romanesque church in Bisceglie, Italy.

Sant'Adoeno is an 11th-century Romanesque church in Bisceglie, built entirely of local limestone on a three-aisle plan without a transept. The central nave has four bays marked by sturdy pillars. The facade has a truncated gable with a small moon-calendar eye in the tympanum, a rose window, and a central mensole bearing a small statue of the saint.

The church was founded in 1074 when Bishop Dumnello assigned it to residents from the hamlets of Cirignano, Primignano, and Zappino. This establishment reflected the settlement and reorganization of the medieval city.

The church is named for Audoin (Sant'Adoeno), a 7th-century bishop of Rouen and protector of the Normans, who reportedly built it. A small relic of the saint, brought from Normandy, is kept inside. The 11th-century baptismal font, on the right of the main portal, bears six high reliefs of Christ's baptism and the Evangelists' symbols.

The church stands in the fortified old town of Bisceglie on Sant'Adoeno street and is easily accessible to visitors. Its central location makes it convenient to explore alongside other nearby historical sites.

The church's 11th-century stone baptismal font, set on a pedestal right of the main portal, carries six high reliefs showing the baptism of Christ and the symbols of the Evangelists. Its restoration was completed in 2010.
