Following the performance at the Kammeroper, we trudged through the snow to what was once an outer suburb of the city, where Haydn bought a house in Gumpendorf (now Haydngasse).  Adding a second storey to a fairly modest dwelling, he lived here from 1797 until his death, composing both The Creation and The Seasons.  The house is run as a branch of Wien Museum, which operates a portfolio of composer-houses across the city.  A new and helpfully bilingual exhibition across the two floors has been created for this bicentenary year.  His highly successful sojourns in London are effectively evoked,  as are the minutiae of his daily life, finances, servants and visitors.  Visit www.wienmuseum.at/english/75.asp
