Istanbul is choc full of exciting things to see but there is one spot that could easily be missed.
It’s the Yerebatan Saray Sarnici, one of the many cisterns the Byzantines built to make sure they had a plentiful supply of water. It's a vast underground space full of elaborate columns and arches, which are reflected in rippling water. Everything is bathed in coloured light and there is soft soothing music.
It's an eerily fascinating atmosphere. You climb the steps and you are suddenly in the bustling streets around the Topkapi Palace.
It’s a great place to go if the streets above are hot! Cool and peaceful.
