New York City Hall is the seat of New York City government, located at the center of City Hall Park. Constructed from 1803 to 1812, the building is the oldest city hall in the United States that still houses its original governmental functions, such as the office of the Mayor of New York City and the chambers of the New York City Council. While the Mayor's Office is in the building, the staff of thirteen municipal agencies under mayoral control are located in the nearby Manhattan Municipal Building, one of the largest government buildings in the world, with many others housed in various buildings in the immediate vicinity.
Although Mangin and McComb designed the building, which was constructed between 1810 and 1812, it has been altered numerous times over the years by several architects. The building consists of a central pavilion with two projecting wings. The entrance, reached by a long flight of steps, has figured prominently in civic events for over a century and a half. There is a columned entrance portico capped by a balustrade, and another balustrade at the roof.
On the inside, the rotunda is a soaring space with a grand marble stairway rising up to the second floor, where ten fluted Corinthian columns support the coffered dome, which was added in a 1912 restoration by Grosvenor Atterbury. The rotunda has been the site of municipal as well as national events. Abraham Lincoln's coffin was placed on the staircase landing across the rotunda when he lay in state in 1865 after his assassination. Ulysses S. Grant also lay in state beneath the soaring rotunda dome – as did Colonel Elmer Ephraim Ellsworth, first Union officer killed in the Civil War and commander of the 11th New York Volunteer Infantry Regiment.
There are 108 paintings from the late 18th century through the 20th. Among the collection is John Trumbull's 1805 portrait of Alexander Hamilton, the source of the face on the United States ten-dollar bill. There were significant efforts to restore the paintings in the 1920s and 1940s.
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.
