The Palazzo dei Normanni (Norman Palace) was the seat of the Kings of Sicily during the Norman domination and served afterwards as the main seat of power for the subsequent rulers of Sicily. The building is the oldest royal residence in Europe; and was the private residence of the rulers of the Kingdom of Sicily and the imperial seat of Frederick II and Conrad IV. The palace stands in what is the highest point of the ancient centre of the Palermo.
The first building, the al-Qasr (in Arabic, castle or palace) is believed to have been started in the 9th century by the Emir of Palermo. Parts of this early building are still visible in the foundations and in the basements, where typical Arabian vaults are present. After the Normans conquered Sicily in 1072 and established Palermo as the capital of the new County of Sicily, the palace was chosen as the main residence of the kings. The Norman kings transformed the former Arabian palace into a multifunctional complex with both administrative and residential aims. All the buildings were linked to each other via arcades and enclosed by gardens, designed by the best gardeners of the middle east. In 1132 King Roger II added the famous Cappella Palatina to the complex.
During the reign of the Swabian emperors, the palace maintained its administrative functions, and was the centre of the Sicilian School of poetry, but was seldom used as permanent seat of power, especially during the reign of Frederick II.
The Angevin and Aragonese kings preferred other seats. The palace returned to an important administrative role in the second half of the sixteenth century, when the Spanish governors chose it as their official residence, carrying out important reconstructions, aimed at their representative needs and their military ones, with the creation of a system of bastions.
The Spanish Bourbons built additional reception rooms (la Sala Rossa, la Sala Gialla e la Sala Verde) and reconstructed the Sala d'Ercole, named for its frescos depicted the mythological hero, Hercules.
The palace contains the Cappella Palatina, by far the best example of the so-called Arab-Norman-Byzantine style that prevailed in the 12th-century Sicily. The wonderful mosaics, the wooden roof, elaborately fretted and painted, and the marble incrustation of the lower part of the walls and the floor are very fine. Of the palace itself the greater part was rebuilt and added in Aragonese times, but there are some other parts of Roger's work left, specially the hall called Sala Normanna.
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.
