The photograph showcases an elegant window in the Art Nouveau style with elements of Spanish-Catalan architecture, characteristic of Barcelona's modernism from the early 20th century. The window is framed by a semi-circular arch made of light-colored stone and adorned with decorative elements.
The upper part of the window opening is decorated with a terracotta ornamental insert featuring geometric patterns resembling stepped forms and stylized battlements. Green decorative elements that frame this composition create a striking color contrast with the terracotta. On the sides of the arch, there are sculptural relief elements in the form of fantastic creatures or dragons.
The window itself consists of two shutters with dark gray louvered panels. Below the window is a wrought iron balcony with an elegant openwork floral pattern, and beneath it — a decorative horizontal frieze with an embossed terracotta ornament.
The building wall is faced with light rectangular tiles, creating a neutral background that highlights the expressiveness of the window's decorative design. The entire composition demonstrates the characteristic Art Nouveau combination of functionality with rich decorative elements and the use of diverse materials and textures.
