Topkapı Palace

Cankurtaran, 34122 Fatih/İstanbul, Türkiye

The primary residence of the Ottoman Sultans for nearly four hundred years remains a sprawling masterpiece of imperial architecture. Unlike many European single-block palaces, Topkapı consists of a series of beautiful pavilions and lush courtyards. The Harem section features some of the finest examples of handmade Iznik tilework found anywhere in the world. Its Imperial Council Chamber displays the classical Ottoman transition from Byzantine influences to a distinct local aesthetic. Today, the complex serves as a massive museum housing the sacred Islamic relics and the famous Spoonmaker's Diamond.

Alemdar, Yerebatan Cd. 1/3, 34110 Fatih/İstanbul, Türkiye

Often called the Sunken Palace, this is the largest of several hundred ancient cisterns located beneath the city.
