St. Stephen's Cathedral in Vienna, with the Kapellhaus (headquarters for the music director and his establishment) in the foreground. The Kapellhaus was Haydn's home when he served as a chorister at the cathedral and composed the Missa brevis. It was torn down in 1804, a year before the elderly Haydn re-encountered his early work.
The Missa brevis in F major, Hob. XXII:1, is a mass by Joseph Haydn originally completed around 1750. According to Dack it is Haydn's "earliest authenticated work." It also represents some of the last of his compositional activity, as in his old age he spent some time attempting to revise it.
