Pergola Shadows Grid on Sfax Atrium Patio

Pale limestone walls curve upward to meet a high vaulted ceiling, defining the spacious atrium in Sfax. Late afternoon light falls through an overhead pergola structure, projecting a sharp, geometric grid of dark shadows across the smooth stone floor. The indirect illumination bouncing off the surrounding walls softens the contrast, allowing the linear pattern to stretch long and steady. Dust motes remain suspended in the quiet air, visible only where the light strikes the textured surface. Along the base of the curved wall, the shadow edges soften into a gentle gradient, marking the turn of seasons with a subtle shift in the light's angle. The pattern ends abruptly at the wall's curve, where the rigid lines dissolve into the plain, unadorned plaster.
