The Suzdal Kremlin is the oldest part of the Russian city of Suzdal, dating from the 10th century. Like other Russian Kremlins, it was originally a fortress or citadel and was the religious and administrative center of the city. It is most notably the site of the Cathedral of the Nativity. Together with several structures in the neighboring city of Vladimir, it was named a UNESCO World Heritage Site in 1992.
While archeological evidence suggests that the Suzdal Kremlin was settled as early as the 10th century, the fortress itself was built in the late 11th or early 12th century. The fortress was strategically located on a bend of the Kamenka river on three sides and a moat to the east. It was surrounded by earthen ramparts that remain to the present day. A settlement to the east became home the secular population - shopkeepers and craftsmen, while the Kremlin proper was the home of the prince, the archbishop, and the high clergy.
From the 13th to the 16th centuries, several monasteries and churches were constructed, including the Cathedral of the Nativity, the Convent of the Intercession, and the Monastery of Our Saviour and St. Euthymius.
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.
