"Fat ships and broad barges filled the river, and tall granaries sprawled along the far bank, but Cairhien seemed to be laid out in a precise grid behind its high, gray walls. Those walls themselves made a perfect square, with one side hard along the river. In just as exact a pattern, towers rose within the walls, soaring as much as twenty times the height of the wall, each one ending in a jagged top." (Robert Jordan, The Great Hunt, p. 367)
