From the Conquest to the 19th century they ruled from it: Topkapi — four courts and the Harem wings, the treasury's emerald dagger and Spoonmaker's diamond, and the Sacred Relics chamber whose Prophetic holdings hearts seek before eyes. The Relics keep continuous Quran recitation — visit in its reverence and dress; the Harem's extra ticket earns itself as the palace's finest tilework; nearly a full day with gardens and the fourth court's Bosphorus view — start early and take your ease.
