The Grand Ballroom in Dolmabahce Palace is the most amazing single room I've ever been in. There is the largest chandelier in the world (weighing 4 tons), and grandeur everywhere. To top in off, there are wonderful gardens and fountains, and it's all along the shores of the Bosphorus and easily accessible by public transportation.
This decadent palace overlooking the Bosphorus in Europe holds great importance to Turkey. The late-19th-century Ottoman sultans resided and ruled the Ottoman Empire from here, and when the Turkish Republic’s capital was located in Ankara, the first president, Mustafa Kemal Atatürk, stayed in the palace whenever he visited Istanbul. He took his last breaths here on November 10, 1938 at 9:05 am—the time still displayed on the clocks in the palace today.
