Editor’s Note:The lure of the exploring the city’s secret corners extends beneath the streets for photographer Brendan Clinch. He’s poked his nose into subway and train tunnels, and even braved the city’s sewers, smell be damned. All of these subterranean places have much to tell us about the city’s growth and development, and thanks to Hidden City contributor and Philadelphia Water Department historian Adam Levine and others, we have access to a good part of the story–just follow the links below. Levine’s wonderful account of exploring the city’s sewers can be read HERE.
