Pope Francis kicked off a whirlwind tour of New York City Thursday with a Mass at the iconic St. Patrick’s Cathedral, before making stops at the United Nations, the Sept. 11 Memorial at the World Trade Center, a school in Harlem, Central Park and Madison Square Garden—all in two days. Here’s what the visit of this highly popular pope looked like, in photos.

He arrived at John F. Kennedy Airport Thursday afternoon, flying in from Washington, D.C., where he met with President Barack Obama and addressed a joint session of Congress.

One downside to the pope’s visit was the traffic—roads closed, paths rerouted, delays on public transit. "There will be a number of street closures and anticipated traffic delays in the area of Central Park West, East Harlem, Financial District, Midtown, Madison Square Garden, and the Upper East Side," the city said before his visit .

After addressing the General Assembly, Pope Francis headed downtown to the World Trade Center at the Sept. 11 Memorial there. He delivered an address and participated in a meeting.

Pope Francis was scheduled to visit East Harlem for a meeting with third-grade students at Our Lady Queen of Angels school Friday afternoon. He planned to then embark on a short drive through Central Park on the Pope Mobile, entering on the West Side and exiting at 60th St.

Before and during his visit, vendors sold miniature statues and other swag, like keychains, T-shirts and magnets, to honor his visit.
