City guide

Istanbul

Istanbul straddles the Bosphorus strait, spreading across both Europe and Asia, with a historic core of Ottoman and Byzantine monuments packed into the Sultanahmet peninsula. Ferries cross constantly between continents while the Grand Bazaar and Galata Tower anchor a city that is equal parts imperial capital and modern metropolis.
