A row of four framed abstract artworks hangs on a white textured wall

A row of four framed abstract artworks hangs on a white textured wall. The artworks are square, black-framed shadow boxes, each containing a silver, fan-like sculptural element. The frames are angled slightly away from the wall. The first artwork, on the far left, is the largest, followed by three progressively smaller artworks to its right. A white ceiling with a perforated pattern is visible at the top of the image, and a white baseboard runs along the bottom of the wall. A framed diagram, possibly an evacuation plan, is affixed to the wall to the right of the fourth artwork. The floor appears to be made of light-colored wood or tile. The overall scene suggests an indoor hallway or common area, possibly in a public building or a modern residence. The image does not contain any people or animals. The location in Cascais, Portugal is not discernible from the visual information present in the image.
