"Olinda is certainly not the only city that grows in concentric circles, like tree trunks which each year add one more ring. But in other cities there remains, in the center, the old narrow girlde of the walls from which the withered spires rise, the towers, the tiled roofs, the domes, while the new quarters sprawl around them like a loosened belt."
