The image displays the Walden 7 apartment complex, located in Sant Just Desvern, within the greater Barcelona metropolitan area, Spain. The prominent structure is a multi-story building featuring terraced, Brutalist-inspired concrete architecture extensively covered with lush green vegetation, creating a vertical garden effect. Each floor is distinguished by wide balconies and ledges supporting a variety of plants, including vines, shrubs, and potted flora, contrasting with dark-paned windows. In the foreground, a low, light-colored stone wall with visible mortar lines runs diagonally across the lower left. Behind it, a dense mass of bright green bushes is present, accompanied by silvery-green shrubs displaying small purple flowers. Several tall palm trees with green fronds are positioned throughout the scene, partially obscuring the building and a modern, white, rectangular pedestrian bridge connecting sections of the complex on the right. Further in the background, a darker building with visible external staircases is partially visible through the palm trees. The scene is illuminated by bright daylight under a clear, cloudless deep blue sky. No individuals are present in the image.
