Fortress Within a High-Security Prison

Photorealistic depiction of a massive fortress built into a high-security prison complex. Weathered gray stone walls with crenellations enclose a central fortress keep, surrounded by secure fences, barbed wire, and reinforced gates. Corner watchtowers with slit windows, iron portcullis, and a shallow moat or dry trench add menace. Inside the yard, distant silhouettes of inmates and guards provide scale. The scene is at dawn with cold blue-gray light, mist curling around the wall bases, and rain-slick stones. Rich textures: rough masonry, damp mortar, rusted metal, glassy CCTV domes. Dramatic low-angle composition with strong leading lines toward the imposing gate; color palette of desaturated blues, grays, and earth tones; shallow depth of field keeping the fortress crisp while the background softly blurs.
