Subterranean Philadelphia Tour

You are invited to explore Philadelphia’s hidden underground infrastructure.

Saturday, December 3, 2016

3:00pm - 5:00pm

Sorry, but there are no further RSVP slots available for this event. We’re working on adding a second tour earlier in the day.

There is a second city beneath our feet, an underground world few of us think about very often. Yet so much of modern life depends on what’s buried down there, and so much of Philadelphia’s history has been shaped by its subsurface transit systems.

We’ll be taking subways, trolleys and trains on this tour as we explore the domain of SEPTA, the nation’s sixth-largest transit system by ridership. We’ll discuss the engineering feats that made it all possible, and talk about the mothballed subway stations, monumental train sheds and even the graffiti writers who turned the tunnel walls into their sketchpad. We’ll also delve into hidden infrastructure — the sewers, water mains, gas lines and telecom equipment — that runs below ground. You’ll never look at Philly the same way again!

This tour is limited to 20 people. Cost is $5 per person, but Next City members can register for free (log in for your discount). Registration is required. Please fill out the form below.
