ancient stone maze wall 3d model

The wall is extremely tall and imposing, built from huge irregular weathered stone blocks, approximately 15–20 meters high and 5–7 meters thick. Dark grey and moss-covered limestone, heavily aged and eroded surfaces, deep cracks, chipped edges, realistic stone joints, subtle dirt, wet patches, roots and small vegetation growing between the stones. Strong architectural construction with large individual stone blocks, uneven handmade masonry, realistic physical proportions.

No fantasy ornaments, no glowing elements, no modern objects, no text, no symbols, no weapons, no characters.
