Trani has lost its old city walls and bastions, but the 13th-century fort has been extensively restored as a museum and performance venue and is open to the public. Some of the streets in and around the Ghetto area remain much as they were in the medieval period, and many of the houses display more or less of Norman decoration.
The main monument of Trani is the Cathedral, dedicated to St. Nicholas the Pilgrim, a Greek assassinated at Trani in 1094 and canonized by Urban II. It lies on a raised open site near the sea, and was consecrated, before its completion, in 1143. It is a basilica with three apses, built in the characteristic white local limestone. It has also a large crypt and a lofty tower, the latter erected in 1230-1239 by the architect whose name appears on the ambo in the cathedral of Bitonto, Nicolaus Sacerdos. It has an arch under it, being supported partly on the side wall of the church, and partly on a massive pillar. The arches of the Romanesque portal are beautifully ornamented, in a manner suggestive of Arab influence; the bronze doors, executed by Barisanus of Trani in 1175, rank among the best of their period in Southern Italy.[2] The capitals of the pillars in the crypt are fine examples of the Romanesque. The interior of the cathedral has been widely modernized, but the crypt remains similar to the origins.
Near the harbor is the Gothic Palace of the Doges of Venice, which is now used as a seminary. The Church of Ognissanti which at one stage was the chapel of a Knights Templar hospital has a Romanesque relief of the Annunciation over the door. San Giacomo and San Francesco also have Romanesque facades; the latter, together with Sant'Andrea, have Byzantine domes.
