The article focuses on the study of Beethoven's heroic symphonies, his Third Symphony, the Eroica, and "Wellingtons Sieg." It also mentions the Eroicasaal, a small room in Vienna's Lobkowitz palace where he has first performed Eroica. "The Imaginary Museum of Musical works" illustrates the musical architecture metaphor where a place survives with the music. Eroica's comparison to architecture is due to construction problems successfully resolved in music, according to Romain Rolland. Beethoven's friend and pupil, Ferdinand Ries says that "Eroica" is originally entitled "Bonaparte", but Beethoven changes it when he finds out that Bonaparte has declared himself Emperor. Beethoven later produces "Wellingtons Sieg," which critics consider the particularization of Eroica's abstraction.
