Forgotten Philadelphia provides a richly illustrated survey of landmark Philadelphia buildings that have succumbed to the ravages of time and changing tastes. More than three centuries of masterful architecture, from William Penn's Slate Roof House to Romaldo Giurgola's Liberty Bell Pavilion, demolished only last year, are brought back to life in this beautifully designed book. Writing with obvious affection as well as a deep knowledge of his subjects, Thomas Keels employs photographs, drawings, prints, maps, and architectural plans to revisit these vanished treasures.
