The Wiener Musikverein is erected as the new concert hall run by the Gesellschaft der Musikfreunde, on a piece of land provided by Emperor Franz Joseph I of Austria in 1863.

The plans had been designed by Theophil Hansen in the Neoclassical style of an ancient Greek temple, including a concert hall as well as a smaller chamber music hall.

The building is inaugurated on January 6, 1870.

Today, 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, Boston's Symphony Hall, and the Teatro Colón in Buenos Aires.

None of these halls were built in the modern era with the application of acoustics science, and, with the partial exception of the horseshoe-shaped Colón, all share a long, tall, and narrow shoebox shape.
