Three great Soviet memorials were erected in Berlin after the war, which not only serve as memorials, but also as war cemeteries. The facility in the Treptower Park is the central memorial and with 100,000 square metres the largest of its kind in Germany. The facility, also serving as cemetery for 5,000 Soviet solders, was built between 1946 and 1948 on the site of a large playing and sports field. Memorial slabs and frescos depicting the course of the war are arranged in long tiers of straight lines. The imposing figure on top of the mausoleum shows a soldier carrying a rescued German child. It is a memorial for the app. 80,000 Red Army soldiers killed during the conquest of Berlin in World War II. 40,000 cubic metres of granite were used in the construction. Aside from the war cemetery in Niederschönhausen, the facility is the largest Soviet war cemetery in Germany as well as the largest anti-fascist memorial in Western Europe.
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.
