The Little Hagia Sophia mosque is a former Greek Orthodox church dedicated to Saints Sergius and Bacchus in Constantinople (modern Istanbul). It is nonetheless one of the most important early Byzantine buildings in Istanbul. The construction of this church, between 527 and 536 AD, was one of the first acts of the reign of Justinian I.
After the Ottoman conquest of Constantinople in 1453, the church remained untouched until the reign of Bayezid II. Then between 1506 and 1513 it was transformed into a mosque. At that time the portico and madrasah were added to the church.
In 1740 the Grand Vizier Hacı Ahmet Paşa restored the mosque and built the Şadırvan (fountain). Damage caused by the earthquakes of 1648 and 1763 was repaired in 1831 under the reign of Sultan Mahmud II. In 1762 the minaret was first built. It was demolished in 1940 and built again in 1956.
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.
