PPG stands for Points Per Game in sports stats, or if you're dating a lot of girls at once in England, and you average out how many Pounds Sterling you spend on each one weekly, it comes out to your PPG total (Pounds Per Girl). It also works if you're dating and spending on multiple men... Pounds Per Guy.
In Pittsburgh, though, PPG stands for something totally different and not sports-related (because their sports teams win everything every season anyway, so)... it's the most spectacular and noticeable and memorable building in a very impressive set of stunning downtown skyscrapers.
Pitt is one of the most underrated and stunning cities in the USA, and this building is a significant part of the reason why.
What makes PPG Tower (and indeed the whole plaza) so remarkable is two-fold. Firstly, it's made out of glass... it looks like a huge crystal sculpture... and is enormous. Secondly, and even more of a quirk, is that it's designed with all kinds of pointy turrets like a huge, enormous, disney-esque, futuristic, cartoonish glass castle.
Certainly if buildings all over the world had this sort of imaginative design, then skylines everywhere would be even better for it.
It's my favourite building to wander around, photograph, and visit in Pittsburgh, and the best view of it is from way up atop Grandview Drive on the west side, from one of the many viewing points.
If you're wondering whether or not you should go and visit, all I can say is, PPG. Please, Please Go. read more
