Valle Vigezzo (Vigezzo Valley) is a valley in the Lepontine Alps in northwestern Italy on the border with Canton Ticino of Switzerland. It forms the eastern branch of the Ossola valley. It is also called the Valle dei Pittori (Valley of the Painters) due to the large number of painters over the centuries. It is remembered for its "spazzacamini" or chimney-sweepers who brought their trade around Europe. It is connected with the Eau de Cologne, invented over 300 years ago by Giovanni Maria Farina using, among other ingredients flowers and oils from plants from Vigezzo.
