A group of nuns taking a walk in the gardens of the Belvedere Palace in Vienna.

It was a pleasant day of spring and the sun drove most people outside, in the fresh air. Groups of teenagers could be seen, sitting on the grass, working or chatting, surrounded by herds of disoriented tourists, myself included. In the middle of all the cameras and noisy families on their day off, a group of nuns sat admiring the gardens. I spotted them and took the picture but they never took notice of my presence.
