The photo was taken in September, 2015. You can see the beauty of architecture and find a variety of architectural styles in each street in Vienna. Vienna is also hosting many operas, theatres and museums. I would say Vienna might be the capital of culture. When I was there, it was pretty cold and windy. I would not suggest you to go there in autumn. In winter, this might be a little different since I believe snow makes the city way better to enjoy :)
