Probably built in 837 by Orso I, the Monte Sant'Angelo Castle has bastions of different ages. The most ancient part, called Torre dei Giganti ('Giants' Tower') is a pentagonal tower 18 m-high, with walls 3.7 m thick. The first documents on its history dates back to 979; later, it was the residence of Rainulf I of Aversa and the Robert Guiscard, who built the Norman Tower and the Treasure Hall.
Emperor Frederick II restored the construction to use it as residence for his mistress Bianca Lancia, while under the Angevines it was used mainly as prison. Later, from 1464 to 1485, the fortress was the residence of the exiled Albanian condottiero Skanderbeg. The castle was largely rebuilt in the late 15th century by Ferdinand I. According to a legend, the castle is currently home to the ghost of Bianca Lancia, whose sighs can be heard especially in the winter time. Today the castle is used for exhibitions.

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.
