The image shows an elegant entrance portal of a residential building in the Art Nouveau style. The building's facade is made of gray stone with clearly defined masonry. The focal point of the composition is an unusual rounded arch portal, framed with light-colored bricks that create a soft contrast with the main tone of the facade.
The door, fitted into the arched opening, is made of dark wood with a paneled structure in the lower section. The upper part of the door is adorned with an exquisite green stained glass window featuring decorative metal elements in the Art Nouveau style. The curvilinear metal details form a flowing organic ornament, characteristic of the Art Nouveau aesthetic.
On both sides of the entrance, house numbers 79 and 77 are visible, indicating that the door is located at the junction of two addresses or reflecting peculiarities in the numbering system. The pavement in front of the entrance is made of stone cobbles, emphasizing the historical atmosphere of the building. To the right of the entrance, shutters are visible, adding additional texture to the facade.
Overall, this architectural element represents a beautiful example of urban Art Nouveau from the early 20th century, with its characteristic attention to detail and aspiration toward organic forms.
