The Oratory of San Marco is a Byzantine-style oratory situated in the old town centre of Rossano, a frazione of Corigliano-Rossano.
The church was built in the 10th century by St. Nilus the Younger as a place of retirement for nearby eremite monks and is one of the most important testimonies to Byzantine art in Italy. It is the most ancient monument in the city and was originally dedicated to St. Anastasia. It has a Greek cross plan with five characteristic domes on cylindrical drums and, in the past, the entire building was supported by very thin columns then these were covered with cement after restoration works. Between 1928 and 1934, during the restoration works, a fragment of a fresco picturing a Virgin Hodegetria was discovered.
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.
