The Light of Islam — From al-Andalus to Samarkand, One Light

You walk from the far west to the far east, following mosques raised to bow toward one same direction. From al-Andalus, where red-and-white arches form a forest, to North Africa's oldest courtyard raised in desert stone, to a Persian portal where sky-blue muqarnas rains down, to the Silk Road's heart where three madrasas ring a square — you pass, one by one, four places built from different stone and light.
