Festspielhaus Baden-Baden is widely known throughout Germany, not just for its size — at 2,500 seats, it's the country's largest opera house — but for its eclectic programming. 

Built in 1998, this well-designed concert hall hosts numerous performances from September through July, including many world premier operas, and is a regular stop for highly-acclaimed orchestras such as the Vienna Philharmonic, as well as the top orchestras from Britain and North America.

Frequently ranking as one of the best such facilities in Europe (and often selling out performances), the Festspielhaus is one of the biggest draws to Baden-Baden for music lovers.
