You can visit the San Nicola basilica which is the most popular attraction in the city and houses the relics of St. Nicholas. You could also head to the west side of the old town to find the Castello (Castle), which was known for being used a prison and signal station in the late 1600’s. Lovers of the arts could head to the Petruzzelli Theater which is the fourth largest theatre in Italy and is both a concert hall and an opera house.
