Palaces open outward and castles close inward, and the aerial view is where that difference becomes obvious: formal gardens and long axial courts on one side, concentric walls and a keep on the hardest rock on the other.
Each palace and castle here comes with its aerial view, photographs, video and a full written guide — who built it, how the plan changed, what survives inside, and what visiting involves.
