A beautiful fountain/pool I saw in Istanbul last Summer. It was in an old bath-house, now a market, and connected the ground floor and basement. When the stall-holders saw me sketching they kindly put the water-pump on full, then they were called to prayer and the market closed, ready for the end of the day’s fasting (it was Ramadan/Ramazan).
