London Rising: The Men Who Made Modern London
I picked this up in Mercer Street Books on a recent trip to New York. Not an instant classic, but good. Hollis intelligently picks a few characters and follows them, rather than trying to discuss anyone and everyone. The most central figure is Christopher Wren, but Robert Hooke, John Locke, and a few others feature as well. It gives a good broad-brush view covering a good 60 years of eventful history, without ever getting lost.
The one thing I wish it had was a diagram, or better yet many diagrams. A big chunk of the book is naturally devoted to the building of St. Paul's Cathedral. We've been there--we've even taken the tour--but there's a lot of architecture floating around London Rising, and it would be useful to have a way to visualize it.
Good companion books include Ross King's Brunelleschi's Dome and R. A. Scotti's Basilica.
