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 Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
