The Vietnam Veterans Memorial is a 2-acre (8,000 m²) national memorial in Washington, DC. It honors U.S. service members of the U.S. armed forces who fought in the Vietnam War, service members who died in service in Vietnam/South East Asia, and those service members who were unaccounted for during the War.
Its construction and related issues have been the source of controversies, some of which have resulted in additions to the memorial complex. The memorial currently consists of three separate parts: the Three Servicemen Memorial, the Vietnam Women's Memorial, and the Vietnam Veterans Memorial Wall, which is the best-known part of the memorial.
The main part of the memorial was completed in 1982. The memorial is maintained by the U.S. National Park Service, and receives around 3 million visitors each year.
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.
