The image showcases an exquisite example of Art Nouveau architectural window decoration. The window is framed by sophisticated ornamental elements featuring the flowing, fluid botanical motifs characteristic of the Art Nouveau style. The upper part of the window casing is adorned with rich stucco work displaying symmetrical plant patterns that create the impression of a natural arch above the window.
The lower part of the façade decoration beneath the window is particularly remarkable: it features a striking sun motif with radiating rays, which is a classic element of Art Nouveau. Below this element is a frieze with circular decorative rosettes and smooth curving lines, emphasizing the organic and natural forms so typical of this style.
The window itself consists of a wooden frame with a small ventilation window, behind which light curtains with lace patterns can be seen. The color palette of the decorative elements is a subdued greenish shade that harmoniously combines with the white wall of the building, creating an elegant and refined appearance.
