The image presented shows not a building facade, but a sample of decorative ornamental pattern in the Art Nouveau style. This is an elegant floral pattern on a green background with white or silver stylized floral motifs.
The pattern is characterized by a symmetrical composition of repeating elements: gracefully curved stems, five-petaled flowers, and decorative leaves resembling thistles. The flowing organic lines and botanical forms are typical of Art Nouveau aesthetics from the late 19th to early 20th century.
Such decorative elements were often used in Art Nouveau interiors for wallpapers, textiles, and other decor elements. This ornament resembles the works of William Morris and other designers of the Arts and Crafts movement, who sought to create aesthetically perfect everyday objects inspired by natural forms.
