The little port of Trani, the ancient Turenum, lies on the Adriatic coast between Bari (30km/19mi southeast) and Barletta (10km/6mi northwest). Trani is the see of an archbishop.
The Cathedral in Trani is finely detailed and contains the Crypt of St Leucius. It is considered one of the most important Greek churches in the province.
On the west side of the harbor in Trani we find the Gothic Palace of Simone Caccetta (15th century) and a little way south of this the church of Ognissanti, with a deep porch, which was formerly a Templars' hospice; above the doorway are Romanesque carvings of the Annunciation and the Tree of Life.
In Molfetta (pop. 65,000), near the harbor, stands the Duomo Vecchio (seventh-eighth century), a Romanesque building, which is considered to be the most important example of a domed church in Apulia.
East of the harbor in Trani, by the Baroque church of San Domenico, are the municipal gardens (Villa Comunale), with three Roman milestones from the Via Traiana which ran from Benevento by way of Canosa, Ruvo, Bari and Egnazia to Brindisi. From the west end of the gardens a view of the harbor and the cathedral can be enjoyed.
Southeast of Trani is Ruvo di Puglia (260m/858ft; pop. 25,000), with a Norman cathedral (12th-13th centuries), which has a fine doorway. The Palazzo Iatta contains a fine collection of vases (sixth-third centuries B.C.) found here.
