The image showcases an exquisite example of Art Nouveau architectural window design. The elongated window with its characteristic curved top is framed by a light-colored stone or plastered portal with the fluid, flowing lines typical of the Art Nouveau style. The stained glass combines geometric patterns in the upper section with floral motifs in the lower part.
The upper portion of the stained glass is adorned with a repeating ornamental pattern featuring floral motifs arranged in a rhythmic grid. The lower part of the composition displays a striking floral design with purple flowers and green leaves, executed in classic stained glass technique using colored glass. The window opening is complemented by an elegant wrought iron railing with floral elements at the base.
The window framing features the flowing lines characteristic of Art Nouveau's organic aesthetic, while beneath the window sits a decorative frieze with a relief plant ornament clearly showing four flowers with four petals each. This attention to detail and the pursuit of stylistic unity from major architectural forms down to the smallest decorative elements is a distinguishing feature of Art Nouveau architecture from the late 19th to early 20th century.
