Five of the best free attractions in Istanbul, Turkey, from haggling in the city's markets to exploring the Florence Nightingale Museum.

Admire the Blue Mosque

The architecturally beautiful Blue Mosque is distinctive for its array of cascading domes and six glittering minarets. Commissioned in the 17th century by Sultan Ahmet I, the Blue Mosque – so called because of the 20,000 blue tiles that adorn its domed ceilings – was designed to rival neighbouring Hagia Sophia. Pause to admire the mosque’s impressive main entrance, but note that non-worshippers must enter via the north gate. Open daily 0930 – 1730; closed to non-Muslims during prayer times.
