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.
The castle was commissioned by Frederick II of Swabia in 1230. It was completed three years later, although consolidation of the structure continued for a further fifteen years. Like many other castles, it was modified in the 16th century when Charles V reinforced the defensive structure by adding two bastions equipped with fire arms.
The Castle, with its quadrangular base, is one of the finest existing examples of Swabian defensive architecture. Originally featuring square-base towers on each corner and a central courtyard, it was later fortified with the addition of an external wall. It stands by the sea and was, in the past, directly linked to the water. It used to have a wooden drawbridge.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
