Open house, free admission, full program: the upcoming edition of the Fratopia Festival has some innovations in store. Because the basic idea of the festival - an invitation to discover and re-listen to classical music - we have radically rethought. For five days, the Alte Oper is open to everyone, from the afternoon until late in the evening. A top-class program of short concerts awaits you in the various halls of the house. And with it, the cordial invitation to simply drop by - without a plan and without a ticket, but with an appetite for innovative concert formats and encounters!
