wooden cabinet or door with a rectangular frame

wooden cabinet or door with a rectangular frame. The wood is a light brown color with visible grain patterns. Two decorative rope knots are attached to the door; one is a larger knot with a short tail, and the other is a smaller knot shaped like a figure eight. A red sign with text in a Cyrillic script is affixed to the left side of the wooden frame. The door or cabinet is viewed from a low angle, with the ceiling visible on the left. The Cyrillic word on the sign appears to be "НУЖНИ," which could potentially translate to "needed" or "necessary." The location is not discernible from the provided image alone. However, given the prompt mentioning Varna, Bulgaria, there is a high probability the image was taken in this location. Without additional data, it is only possible to confirm that the photograph shows a detail of the cabinet or door inside the building.
