The Christian Museum of the Cathedral in Cividale del Friuli/Čedad is divided into two sections: The Lombard heritage and the Treasure of the Cathedral. The most significant piece of the Lombard heritage is undoubtedly the Ratchis Altar from the 8th century, named after the Duke of Friuli who commissioned it. Ratchis later became King of Lombard Italy. Another important monument is the Baptistery of Callisto which was commissioned by Callisto, the first Patriarch of Aquileia (731 A.D) to move to Cividale.
The Treasure of the Cathedral presents the absolute prestige of the old Christian history of the ancient capital. Displayed are jewellery, liturgical objects, manuscripts, sculptures, etc.
