Last night I went on a walking tour with the Pittsburgh Landmarks and History Foundation. We were looking at buildings designed by New York architects. It was a beautiful evening and a great way to learn more about Pittsburgh. This sculpture, by Kenneth Snelson, wasn’t really on the tour, although we walked past it.
I really loved it because the sparrows are using it to land on and possibly are nesting inside the tubes. I saw several of them walk into it.

The PPG Tower(s) were built by Phillip Johnson, a New York architect. We only viewed it at a distance but I walked around taking some pictures by myself. Photos are in my Pittsburgh Towers album.
