Istanbul

Istanbul straddles two continents and offers one of the richest concentrations of historic monuments in the world, including the Hagia Sophia, the Blue Mosque, Topkapi Palace, and the Grand Bazaar. Cruise ships dock at Galataport in the Karaköy district, steps from the historic Beyoglu neighborhood, with the old city of Sultanahmet a short tram ride away. The Bosphorus strait, visible from much of the city, separates Europe from Asia and adds to Istanbul's singular geography.

A city spanning two continents, with Hagia Sophia and the Grand Bazaar at its heart.
