Roof Core Sample Box on Scaffolded Portugal Facade

Wet terracotta tiles gleam under soft morning light on a scaffolded building facade in Portugal. A white rectangular box containing a cylindrical roof core sample rests on a green metal scaffold plank, its surface slick with recent rain droplets. The box bears printed labels and a small window revealing the dark, layered earth of the roof structure inside. Behind it, blue safety nets hang loosely against the white stucco wall, while wooden planks form the temporary walkway. The sky above is a pale, washed-out blue where clouds are breaking apart. Sunlight catches the wet edges of the scaffold poles, creating thin lines of white reflection on the rust-colored metal. The box sits firmly against the rough texture of the wet wood.
