Looming over the point where the Golden Horn meets the Marmara Sea, Topkapı Palace was the primary residence of the Ottoman sultans for more than four centuries. Among the gems of the historic peninsula, Topkapı’s extensive rooms, chamber houses and fascinating objects, including the 86-carat Spoonmaker’s Diamond, make the museum a must-see. In addition to its extensive and illustrious permanent collections of weaponry, precious jewels, and religious artifacts, it is also home to a rotating cast of temporary exhibitions.
