There is a tunnel in Utrecht that leads from the Ganzenmarkt to the Oudegracht wharves.  I discovered the tunnel by chance after a late night in the town as part of the conference dinner.  Walking back to my hotel, I passed by the restaurants and the bars.  My eye caught a flashing light and I looked over the railing and saw colourful lights radiating out of a tunnel close to the canal.  I walked down and found this colourful psychedelic tunnel.  The lighting of the tunnel kept changing and there were three people dancing in what looked like a trance.  They were oblivious to my presence and so I took some pictures and then headed home.  

The next morning I retraced my steps to the tunnel. The location is a photographer’s dream site for pictures especially as the colourful lights are constantly changing on a regular cycle.  The street art is colourful and the illumination provides a changing backdrop.  I asked a colleague to return with me so that I could place him at the entrance then use his silhouette to provide a focus to the pictures.  Enjoy the result.  Sorry if it is somewhat self-indulgent but it was such a great place to photograph.
