I had never been around to the rear of the new-ish Art Gallery of Ontario transformation (Frank Gehry) until last Friday when I found myself with some time to kill between dates. I settled onto a bench on Grange Park and enjoyed the sun and a good book. The back of the gallery is such a contrast to the front, yet almost as interesting. The shots above are from my iPhone, so not the greatest of quality.
Below, an image of the front facade from the AGO website.
Also from the AGO website, a shot of the staircase (above) from the inside.
