Windmill in a Monastery Courtyard - 3D Render

Photorealistic 3D render of a windmill integrated into the courtyard of a medieval monastery. The windmill is built against a weathered limestone wall, perched on a circular stone base with dark wooden sails turning slowly, catching warm golden-hour light. Surrounding architecture features a stone cloister with tall pointed arches, carved capitals, and ivy climbing the columns. The courtyard ground is worn flagstone with patches of moss and small reflective pools. Soft volumetric light beams pass through the arches, dust motes float in the air, and distant hills glow in hazy light. Render with Physically Based Rendering (PBR), global illumination, ambient occlusion, depth of field, and 4K resolution. Palette of warm ochres, cool stone grays, and deep greens; mood is tranquil, historic, and contemplative.
