Istanbul

Istanbul is Turkey’s largest city and the only one in the world spanning two continents, where Roman, Byzantine, and Ottoman history sit side by side across the Bosphorus.

Where to stay in Istanbul

Sultanahmet puts you inside walking distance of Hagia Sophia, the Blue Mosque, and Topkapi Palace, but it’s also the most tourist-heavy, priciest-per-square-foot part of the city. Beyoğlu costs less, eats better, and is a 15-minute tram ride from the old city. Kadıköy on the Asian side is quieter and better value if you don’t mind a ferry into the historic core.

Best things to do in Istanbul

Hagia Sophia

Built as a Byzantine cathedral in 537 AD, converted to a mosque under the Ottomans, and now a working mosque again — Hagia Sophia is the single structure that best summarizes Istanbul’s layered history. Entry is free but lines build fast after 10am; arriving at opening avoids the worst of it.

Blue Mosque

Directly across the square from Hagia Sophia, the Blue Mosque is named for the İznik tilework lining its interior — over 20,000 handmade tiles in blue and turquoise patterns. It’s an active place of worship, so it closes to visitors briefly during the five daily prayer times.

Grand Bazaar

One of the world’s oldest covered markets, with over 4,000 shops across 61 streets. Prices aren’t fixed — bargaining is expected and part of the experience. Go early on a weekday morning for a quieter walk before the tour groups arrive.
