Thanks to his architectural landscapes, his portraits and his site specific interventions, he is one of the actually active artists living in this city.

The beginnings of Valle as a painter, belong to his hometown, which under the communism was an industrial basement of petrol.

Petrol is one of the main factors of global changes that regard development and pollution, and Valle through his paintings and other types of work, keeps investigating the negative and 'positive' effect of this exploitation on the everyday life, and its consequences on the living and perception of modern landscape.

Marinz is a small country close to that industrial city where Valle grew.

Since the year 2012 the artist has been painting polluted flowers of Marinz, while taking its land pieces to transform them into art works, by drying and adorning them, acclimating and taming them, making them so to say, domestic.
