Beethoven spent at Eroica House the summer of 1803. He worked on, but didn’t finish, his 3rd symphony "Eroica" which is widely acknowledged as a ground breaking work as well as one of which brought new boldness and harmony to his music. Eroica is the name given to the house where you'll find related pictures and sheet music. Many exhibits in the house remind the world of the still rural Viennese suburb. Beethoven changed his house 79 times during his 35 years in Vienna. The second very famous residence is the Pasqualati House, located at Mölkerbastei 8. It is a house that was owned by Johann von Pasqualati and served as the occasional guest residence of the composer. Having spent a number of years at Pasqualati House, he obviously found its atmosphere conducive to new ideas, as he composed not only the 4th, 5th and 6th symphonies, but the magnificent operetta "Fidelio". Nowadays, there isn't much to see here except some family portraits and the Beethoven's scores, but you might feel it's worth the visit the apartment on the fourth floor (no elevator).
