The Wiener Musikverein is a concert hall in the Innere Stadt borough of Vienna. It is the home of the Vienna Philharmonic orchestra. The 'Great Hall' (Großer Saal), due to its highly regarded acoustics, is considered one of the finest concert halls in the world, along with Berlin's Konzerthaus, the Concertgebouw in Amsterdam, and Boston's Symphony Hall. With the exception of Boston Symphony Hall, none of these halls were built in the modern era with the application of architectural acoustics, and all share a long, tall, and narrow shoebox shape.
The plans were designed by Danish architect Theophil Hansen in the Neoclassical style of an ancient Greek temple, including a concert hall and a smaller chamber music hall. The building was inaugurated on 6 January 1870. A major donor was Nikolaus Dumba, industrialist and liberal politician of Greek descent, whose name the Austrian government gave to one of the streets surrounding the Musikverein.
The Great Hall's lively acoustics are primarily based on Hansen's intuition, as he could not rely on any studies on architectural acoustics. The room's rectangular shape and proportions, its boxes and sculptures allow early and numerous sound reflections.
Today Musikverein is the most used venue for the annual Vienna New Year's Concert.
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.
