St. Paul's Chapel, is an Episcopal chapel located at 209 Broadway, between Fulton and Vesey Streets, in Lower Manhattan in New York City. It is the oldest surviving church building in Manhattan.

The rear of St. Paul's Chapel faces Church Street, opposite the east side of the World Trade Center site. After the attack on September 11, 2001...St. Paul's Chapel served as a place of rest and refuge for recovery workers at the WTC site.

For eight months, hundreds of volunteers worked 12 hour shifts around the clock, serving meals, making beds, counseling and praying with fire fighters, construction workers, police and others. Massage therapists, chiropractors, podiatrists and musicians also tended to their needs.

The church survived without even a broken window.
