Istanbul Old City Mystery
Walk the historic peninsula from Hagia Sophia to the Galata Bridge — Byzantine cisterns, Ottoman palaces, covered bazaars and the bridge over the Golden Horn. About 4 km through the heart of Sultanahmet and Eminönü.
- Topkapi Palace — Imperial Gate — The Imperial Gate (Bab-ı Hümayun) is the main entrance to Topkapi Palace, commissioned by Mehmed II in 1478. From inside these walls, Ottoman sultans and a court of up to 4,000 people governed an empire that at its peak stretched from Vienna to the Persian Gulf. You can walk through the gate into the First Courtyard for free — the entrance ticket is only needed for the museum gate further in, so this stop costs nothing.
- Hagia Sophia — You're standing before one of the world's great buildings. Hagia Sophia was completed in 537 AD under Emperor Justinian I; its dome was the largest in the world for nearly a thousand years. It has been a cathedral, a mosque, a museum, and — since 2020 — a mosque once again.
- Basilica Cistern — Beneath the street lies a Byzantine water chamber built by Justinian I around 532 AD — 336 marble columns holding up a vaulted ceiling, with up to 80,000 cubic metres of water once stored here. In the northwest corner, two columns rest on upturned Medusa heads. No one fully understands why.
