 The "Ostflügel" (East Wing) of the castle was rebuilt after the destruction to serve as a tennis court.Tatiana von Metternich-Winneburg, a co-founder of the Rheingau Musik Festival, turned the hall into a public concert venue, staging 10 of the 19 concerts of the first summer season in 1988, and many recitals and chamber music performances every year following.After her husband's death the hall was named "Fürst-von-Metternich-Saal".
