Hands down one of my favorite Hidden City articles in recent memory, Crane City 2016 takes the reader on a first-hand tour of a multitude of tower cranes throughout Philadelphia at a time when the city is seeing explosive growth. I don't think there has been a development boom like this in Philadelphia's history, and I'm so glad that it's coming at a time when I can experience it directly. The skyline today is so much different than it was 10 years ago, and it's thrilling to watch it transform into a completely different monster that developers probably never expected when One Liberty Place became the first to rise above City Hall in 1986.
Bradley Maule, author of Crane City 2016, formerly headed up his old project at phillyskyline.com which is an absolute treasure trove of development history and construction photos. I really recommend checking it out.
