The much bigger fortress on the European bank of Bosporus, Rumeli Hisari (Rumeli Fortress), was in the shadows of impending nightfall already and only still collected the last rays of sunshine on the back of its big towers.
Burak Sansal's site on "All about Turkey" says:
"Sultan Mehmet the Conqueror built Rumeli Fortress in four months only and directly opposite to Anadoluhisari in 1452 in preparation for the final attack on Constantinople (Istanbul), which led to the downfall of the Byzantine Empire."

Then (or earlier? - to be honest, I don't remember) the guide on the boat announced we would see the oldest house built on the Anatolian bank of Bosporus on our right, and I looked and saw TWO houses that seem to be pretty old already, and since I couldn't quite make out WHICH of the two would possible be the oldest, I took photos of both. Maybe someone knows and can let me know which of these two really is the oldest?

So, that was to be the end of the sun lighting up the buildings - now it was time for the sun to set behind the skyscrapers of Istanbul Business Centre.

Looking back in the direction where we came from, the highly risen buildings of the Business District sparkled, as they still caught the very last bit of sunshine, and the pink coloured building of the Ministry of Health (if I understand things right...) went very well with the pink colour of the evening sky.

Before the light faded altogether with the sun now set, everything was bathed in some soft orange-pink, such as Bosporus Bridge, or in deep yellow, like that newly-being-erected skyscraper of the Business district and the unknown mosque somewhere in its vicinity.

And when we finally arrived at the pier right across the road from the restaurant where we were going to have dinner, night had finally fallen and the sky was a deep purplish blue when our boat left from the pier.

The guide on the boat had said that the banks of Bosporus at night would look like "diamonds" with all the lights on, so when we left the restaurant again, and when night had fully fallen, I just had to take this quick photo of that (unknown to me) part of Istanbul before we were all herded back into the bus to be taken to our hotel overlooking the Golden Horn.
