The project comprises the scenographic development process, together with the conception and realisation, of an illustrative mural for the exhibition area “living spaces and their inhabitants” in the new Natural History Museum of St.Gallen, which opened in 2016. The 400-square metre hall, which at the same time constitutes the heart and centre of the museum, offers a presentation of the flora and fauna of Eastern Switzerland. The mural was created in a work project extending over several years, comprising both research on the content, development of suitable pictorial ideas and guidance for the painters. The picture covers three walls, is 50 metres in length and reaches a height of up to eight metres. A spatial illusion is created by some 50 stuffed animals and six dioramas distributed around the hall in a realistic context. The display thus succeeds in being both instructive and atmospheric.
