I just made my first trip back to Pittsburgh since we moved to Raleigh-Durham back in May. In addition to seeing first hand how it looks like a bomb was dropped on Market Square, I managed to check out PNC Financial's Living Wall at their headquarters on 5th Avenue. Very neat! In case you missed our earlier post about the proposed wall, Fast Company has the details on The Green Wall of Pittsburgh. Could this finally be the start of what I referred to as the transformation of Pittsburgh's Golden Triangle to The Green Triangle? Here is a post from over two years back where I envisioned a downtown of green roofs and green spaces. The new Market Square and PNC's living wall are a step in the right direction.
