If you are a music freak, you must visit the celestial Bayreuth Festival. You’ll get to witness some of the greatest opera performances composed by the famous German composer Richard Wagner.
From the history, it’s clear that Albert Schweitzer was a music lover. He often visited operas of Richard Wagner in Strasbourg. As a music enthusiast, he once got the opportunity to visit the Bayreuth Festival to see Wagner's Der Ring des Nibelungen and Parsifal in 1896. He described that show as one of the most impressive shows he had ever witnessed.
