1. Hagia Sophia (Ayasofya)
A symbol of Istanbul’s layered history, Hagia Sophia has served as a cathedral, a mosque, and now functions as both a historic site and a place of worship. Its massive dome and stunning mosaics reflect a blend of Christian and Islamic influences.
Travel Tip: Visit early in the morning to avoid long lines.
2. Topkapi Palace
Once the heart of the Ottoman Empire, Topkapi Palace is filled with stories of sultans, royal families, and court traditions. Highlights include the Harem, the Imperial Treasury, and breathtaking views over the Bosphorus.
3. The Grand Bazaar (Kapalıçarşı)
One of the world’s oldest and most famous markets, the Grand Bazaar is a sensory overload. With thousands of shops, it’s a great place to shop for handmade carpets, jewelry, ceramics, and spices.
4. Bosphorus Cruise
Taking a cruise along the Bosphorus Strait is one of the best ways to see Istanbul’s skyline. You’ll pass by Ottoman palaces, ancient forts, and the elegant bridges that connect Europe and Asia.
5. Blue Mosque (Sultanahmet Camii)
This iconic mosque is known for its six minarets and the intricate blue İznik tiles that decorate its interior. It’s still an active place of worship, so be sure to dress modestly when visiting.
6. Gulhane Park
Located next to Topkapi Palace, Gulhane Park offers a quiet escape from the busy city streets. It’s especially beautiful in spring when the tulips are in full bloom.

Beneath the city lies the mysterious Basilica Cistern, an underground water reservoir supported by hundreds of ancient columns. The soft lighting and reflective water make it an atmospheric and unforgettable stop.
