Michelangelo, God's Architect

I distinctly remember first learning about Michelangelo in first-grade art class. My interest was sparked then and, up to now, I thought I had a decent grasp on his works and career. Apparently not. I missed out on the entire architecture career toward the end of his life. Needless to say, I learned a lot from this book. 

While works like the Pieta and Sistine Chapel were mentioned as well as a later-in-life biography, the book mostly focuses on Michelangelo's work for various Popes and namely helping to design St. Peter's Basilica. Having taken this on at an advanced age, he of course didn't live to see its completion, however, it still stands today along with his several other famous works.
