The image showcases an exquisite example of a decorative architectural element executed in an eclectic style with clear influences of Art Nouveau and Eastern architecture. We are looking at the upper part of a doorway or window, adorned with an elegant semi-circular crown.
The structural base is made of light green material (possibly painted metal or wood) forming a geometric lattice ornament. The upper semi-circular part is decorated with repeating elements resembling stylized fans or rays, creating a rhythmic composition.
The central accent is a large semi-circular fan-shaped element with alternating brown and golden inserts that imitate mother-of-pearl or stained glass. These inserts create a play of light and color, adding sophistication to the facade. Similar decorative panels are also integrated into the vertical and horizontal elements of the lattice, creating a unified composition.
The lower part is adorned with elegant curls and rings reminiscent of the wrought iron elements of early 20th century Art Nouveau. The entire design demonstrates the fine workmanship of artisans who combined functionality with decorative qualities characteristic of a period when architecture sought a synthesis of arts.
