The image showcases a notable architectural element of a facade - a semicircular window with decorative framing. The window is executed in the Art Nouveau style, which is particularly evident in the characteristic metal elements with smooth, organic lines.
The arched window is framed by massive stonework of pinkish rough-cut stone. The architect created an expressive contrast between the texture of the unprocessed stone and the elegant metal details. Above the window is a decorative metal element with curls and wave-like lines characteristic of Art Nouveau, which serves as both a functional ornament and a visual extension of the window frame.
The window itself has a wooden frame of brownish hue with vertical divisions. On the glass, there are decorative elements in the form of stylized plant motifs, probably made by etching or painting. The lower part of the window is adorned with an elegant metal grille with symmetrical curls, which harmoniously combines with the upper decorative element, creating a unified composition.
This fragment of the facade demonstrates attention to detail and the desire of Art Nouveau architects to combine functionality with aesthetics, where each element not only fulfills its practical role but is also part of the overall artistic concept.
