We begin our tour at Topkapı Palace, which, from the 15th to the 19th century, was the principal residence of the Ottoman Sultans. We will visit the fabulous Imperial Treasury and the Baghdad Kiosk. Topkapı Palace is now a museum and has unrivalled collections of jewelry, including the Spoonmaker’s Diamond, the 3rd largest in the world. It also possesses numerous Ottoman court costumes and ceramics, notably including one of the world’s finest collections of Chinese celadon ceramics, many of which were gifts from other rulers. Interestingly, some of the ceramics have a special glaze that was said to change color in the presence of poison. We also visit the Imperial Armory, displaying centuries of Ottoman weaponry. But perhaps the loveliest feature of Topkapı Palace are its courtyards with their ancient trees; it is easy to imagine the sultan strolling here far from the cares of state and empire. Last but by no means least
