Stone Age Castle Concept Art: Primitive Fortress

An epic Stone Age fortress-castle perched on a jagged hill under a stormy sky. Constructed from rough-cut granite blocks, rammed earth, and timber beams; no metal—only stone, bone, and hide. Crude, crenellated ramparts surround a moat-like ditch; watchtowers rise from stone plinths with conical thatch roofs; a heavy timber gate reinforced by bone pins opens to a central keep built from rough stones, with a blazing hearth glowing through narrow slits. Perimeter palisade of sharpened logs and bone ornaments; inside the courtyard, clan banners made from hides bear primitive animal-symbols. Outside, hunters in fur robes roam the twilight path. Distant mountains loom; the scene bathed in warm torchlight and golden hour glow; misty atmosphere, dramatic shadows, painterly, cinematic concept art style with high detail. 16:9 wide shot, slight aerial perspective, painterly textures, earthy palette of ochre, stone gray, moss green, and amber.
