Most travellers cruise the Bosphorus by day and leave thinking they have seen it. They have seen half of it. After dark the strait stages a second, quieter show that — for my money — beats the daytime one. Floodlights turn the waterfront into a gallery: the Dolmabahçe Palace burns warm gold against the black hill behind it, its 600-metre marble front doubled in the dark water below.
A few minutes on, the Ortaköy Mosque glows white from within beneath the Bosphorus Bridge, which is itself running through slow cycles of coloured LED. The Maiden’s Tower sits out on its little islet like a lamp left on for someone. Rumeli Fortress is lit to throw its medieval walls into relief, and even the wooden yalı mansions wear soft uplighting that picks out their carved facades. Put all that against slow-moving dark water that mirrors every light twice, and you have a sight that genuinely belongs to Istanbul and nowhere else.
