The New York Stock Exchange Building (NYSE Building) is a structure in the Financial District of Manhattan, serving as the headquarters of the New York Stock Exchange. It is composed of two connected structures occupying two-thirds of the city block bounded by Wall Street, Broad Street, New Street, and Exchange Place. The central third of the block contains the original structure at 18 Broad Street, designed in the neoclassical style by George B. Post. The northern third contains a 23-story office annex at 11 Wall Street, designed by Trowbridge & Livingston in a similar style.
The marble facade of 18 Broad Street contains colonnades facing east toward Broad Street and west toward New Street, both atop two-story podiums. The Broad Street colonnade, an icon of the NYSE, contains a pediment designed by John Quincy Adams Ward, depicting commerce and industry. Behind the colonnades at 18 Broad Street is the main trading floor, a 22 m rectangular space.
The NYSE had occupied the site on Broad Street since 1865 but had to expand its previous building several times because of overcrowding. The structure at 18 Broad Street was erected between 1901 and 1903, replacing the previous building. Within two decades, the NYSE's new building had become overcrowded, and the annex at 11 Wall Street was added between 1920 and 1922. Three more trading floors were added in the late 20th century to accommodate increasing demand, and there were several proposals to move the NYSE elsewhere during that time. With the growing popularity of electronic trading in the 2000s, the three newer trading floors were closed in 2007.
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.
