Even this picture is nothing special as many tourists have visited  Spanish Riding School in Vienna, I put it here.  It is again the kind of picture, what has story to tell about the past. Look this picture longer and concentrate to details (which there is so much) . It is so easy to see all these centuries passing through.  You can nearly see how now the doors will be opened and horses are running in. This picture can symbolize silence in the middle of big city. It is so difficult to imagine, that just behind this wall there are driving buses and taxis and walking thousands of tourists.
