A gathering place for German intellectuals, the Via del Corso apartment where Johann Wolfgang von Goethe enjoyed a happy Italian sojourn (despite complaining of the noisy neighbours) from 1786 to 1788 is now a lovingly maintained small museum. Exhibits include fascinating Piranesi engravings of 18th-century Rome, as well as Goethe's sketches and letters, plus some lovely sketches of him by his friend Tischbein. With advance permission, ardent fans can use the library full of first editions.
