A thousand years of enchantment around one miraculous square — Jemaa el-Fnaa, UNESCO-listed living heritage that turns nightly into an open theater. The medina core (Koutoubia, souks, Bahia, Ben Youssef), the gardens (blue Majorelle, Atlas-backed Menara), and hour-away escapes (green Ourika, stone-desert Agafay). Sleep in a riad at least two nights; open haggling at a third; winter and spring are gold.
