Build a huge 170x170 open-air modern prison courtyard hub. Make it very wide, heavy, thick, and low-rise. Add deep chunky cell wings on the left and right sides with wide cells, 2 levels, and strong prison massing. Keep clear north and south entrance gateways open and obvious. Put a large cyan 1 fully embedded in the ground, with a gold halo ring also embedded in the ground around it. Keep the center very open for gathering and movement. Bright lighting everywhere at night. Premium, polished, symmetrical, modern prison style. No skulls, no fountains, no extra wings.
