The Library of Congress is the research library that officially serves the United States Congress, but which is the de facto national library of the United States. It is the oldest federal cultural institution in the United States. The Library is housed in three buildings on Capitol Hill in Washington, D.C. The library is the second-largest library in the world by collection size.
The Library of Congress moved to Washington in 1800, after sitting for eleven years in the temporary national capitals of New York and Philadelphia. The small Congressional Library was housed in the United States Capitol for most of the 19th century until the early 1890s. Most of the original collection had been destroyed by the British in 1814 during the War of 1812. To restore its collection in 1815, the library bought from former president Thomas Jefferson his entire personal collection of 6,487 books.
After a period of slow growth, another fire struck the Library in its Capitol chambers in 1851, again destroying a large amount of the collection, including many of Jefferson's books. The Library of Congress then began to grow rapidly in both size and importance after the American Civil War and a campaign to purchase replacement copies for volumes that had been burned from other sources, collections and libraries (which had started to appear throughout the burgeoning United States). The Library received the right of transference of all copyrighted works to have two copies deposited of books, maps, illustrations and diagrams printed in the United States. It also began to build its collections of British and other European works and then of works published throughout the English-speaking world.
This development culminated in the construction between 1888 and 1894 of a separate, extensive library building across the street from the Capitol, in the Beaux Arts style with fine decorations, murals, paintings, marble halls, columns and steps, carved hardwoods and a stained glass dome. It included several stories built underground of steel and cast iron stacks.
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.
