TRAVEL ESSENTIALS
THE CITY IN BRIEF
Founded as Byzantion in the 7th century BCE, the city became Constantinople in 330 CE, capital of the Byzantine Empire and the largest city of its world. After the Ottoman conquest in 1453 it served as the empire's capital for nearly five centuries. Today it is Türkiye's largest city, spread across the Bosphorus strait between Europe and Asia — which is why its architecture reads as a sequence: Byzantine domes, Ottoman mosque complexes, and a contemporary waterfront layer.
For the Byzantine layer behind Hagia Sophia and the cistern, read Byzantine Architecture, Book XXII of the Architectural History Series, free to read online.

Opening hours and ticket availability must be checked live before departure. The route order will update when Google Places is connected.
How the programs relate: the two half-day routes stand alone or combine into a full architecture day — take the morning route, then the afternoon route. The hour-by-hour program further down shows one combined day.
Approximate walking distances — Morning: Hagia Sophia Square → Blue Mosque 300 m; → Basilica Cistern 350 m; → Topkapı first court 600 m; → Gülhane edge 400 m. Afternoon: Galata Tower → SALT Galata 700 m; → Karaköy streets 400 m; → Istanbul Modern 800 m; → Bosphorus ferry pier 300 m. Distances are approximate; use the map links for step-by-step directions.
