What to See at the World Trade Center Site: A Walk Around the Whole Campus

By 17John Hotel · October 1, 2026

• The memorial pools

  · A short walk west of us, at 180 Greenwich Street · Free, outdoors

  This is the reason to come. Each pool drops 30 feet into a square basin (the largest manmade waterfalls in North America), then falls another 20 feet into a central void that never fills. The architect, Michael Arad, called it absence made visible, and the sound of the water genuinely does cut the traffic noise out. The names of the 2,983 people killed in 2001 and in the 1993 bombing are cut into the bronze parapets, and they aren't alphabetical. They're grouped by where people were and who they were with, and families could ask for a name to sit beside a specific other name. Walk the full rim of both pools rather than photographing one corner. That's where the arrangement becomes obvious.

• The Survivor Tree

  · On the memorial plaza, a few steps from the pools · Free, outdoors

  Easy to walk straight past, so look for the one tree that doesn't match the rows. Recovery workers pulled it out of the site badly damaged in October 2001, the Parks Department nursed it back, and it was replanted here in 2010. The oaks around it were chosen because the species grows near all three crash sites. Go in spring if you can time it, when it's the first thing on the plaza in flower.

• The 9/11 Memorial Glade

  · Southwestern corner of the memorial plaza · Free, outdoors

  The quietest part of the site and the part almost no visitor finds, because it's off the direct line between the two pools. It's for first responders, recovery workers, volunteers and residents, not for the day itself. Worth the two-minute detour if you want somewhere to stand that isn't shoulder to shoulder with a tour group.

• Liberty Park and the Koenig Sphere

  · South side of the World Trade Center campus · Free, outdoors

  Go up here for the view back over the pools, which is the shot people spend an hour hunting for at ground level. The sphere stood on the original plaza between the towers and came through the collapse dented but whole. Seeing the damage up close does more than most of the interpretive panels on site. It's also the least crowded corner of the campus on a weekday afternoon.

• The Oculus

  · Centre of the campus, connected underground · Free to walk through

  Come in from the street at least once rather than only surfacing into it from a train, because the point is the ceiling and you can't see it properly from the escalators. It's also the practical answer to weather: you can cross most of the campus underground and stay dry, and there are trains and food down there when the plaza is too cold to stand around on.

• One World Observatory

  · One World Trade Center, on the northwest corner of the campus · Ticketed

  Worth it for a first visit to New York, skippable if you've already picked a different deck. The advantage down here is the harbour: you're looking straight down at the Statue of Liberty, Governors Island and the bridges rather than at other buildings. Book a time slot before you walk over, and go earlier in the day if you want the water clear rather than hazy.

• Perelman Performing Arts Center (PAC NYC)

  · North side of the World Trade Center campus · Ticketed, varies by show

  The reason to look at the campus calendar before you come. Everything else here is about 2001; this is the one building on the site that exists to put something new on. Check what's on the night you arrive, because a show here is a five-minute walk home for you rather than a train back from Midtown. Even if you don't get a ticket, walk past it after dark. The stone façade lights from inside.
