Create a massive ancient overgrown palace complex, roughly 200 blocks wide and 100 blocks tall. Roman-Byzantine style — warm sandstone and smooth stone blocks, slightly yellowed and weathered. Structure has 4 large domes (30–40 blocks wide each) at varying heights, topped with smaller dome cupolas. Tall cylindrical towers flanking the sides, also domed. Every level has wide colonnaded arcades — rows of 20–30 rounded arches with thick columns. Building is heavily tiered, each floor stepping back like a pyramid with open gallery walkways on every level. Grand wide staircase at the front climbing up 3 tiers. Nature is reclaiming it — vines (green concrete/leaves) crawling up every wall, oak and jungle trees growing from rooftops and ledges, moss covering the lower half of all surfaces. Column
