In 963, Canosa was rebuilt at a site below the former Roman city. It remained a Lombard gastaldate until the Norman conquest that established the Kingdom of Sicily. Under Bohemund I of Antioch (d. 1111), son of Robert Guiscard, it regained some of its earlier importance. The 5-domed cathedral of St Sabinus was completed in 1101. Bohemund's tomb is located just to its south. Following the extirpation of the Hohenstaufens, however, it again went into decline.
