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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
