Erected in 1154 as a notable example of the Arab-Norman architecture which flourished in Sicily under Norman rule on the island, the Church of San Cataldo is annexed to that of Santa Maria dell'Ammiraglio. In the 19th century it was restored and brought back to a form more similar to the original medieval edifice.
The church has a rectangular plan with blind arches, partially occupied by windows. The ceiling has three characteristics red, bulge domes (cubole) and Arab-style merlons. The church provides a typical example of the Arab-Norman architecture, which is unique to Sicily. The plan of the church shows the predilection of the Normans for simple and severe forms, derived from their military formation. Moreover, the building shows how international the language of Norman architecture was at the time, as the vocabulary which marks parts of the church, like the bell tower, can be tracked down in coeval buildings like the cathedral of Laon and the Abbaye aux Dames in Caen, both in Northern France, or the cathedral of Durham in England. At the same time, the church shows features shared by Islamic and Byzantine architecture, such as the preference for cubic forms, the blind arches which articulate the external walls of the church and the typical spherical red domes on the roof.
The interior has a nave with two aisles. The naked walls are faced by spolia columns with Byzantine style arcades. The pavement is the original one and has a splendid mosaic decoration. Also original is the main altar.
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.
