Roughly 1,000 tickets are available in the lottery which is open to 9/11 family members, survivors, first responders and recovery workers, as well as those affected by the 1993 World Trade Center bombing, and residents and business owners below Canal Street.
The pope, slated to visit on Sept. 25, will pay his respects at the outdoor memorial, and host an interfaith program, with prayers for peace, inside the museum.
Lottery ticket holders will be able to bring one guest to see the pope. The majority of tickets will give access to the memorial plaza, where the massive pools in the footprint of the destroyed towers rush perpetually with water, as the pope visits the grounds.
Only a "very limited number of seats" will be made available for the pope's "Multireligious Meeting for Peace" hosted inside the museum, according to museum officials.

"Pope Francis has expressed the importance of preserving the living memory of others," said Museum president Joe Daniels in a statement. "For many around the world, including those who experienced 9/11, there is no more important a place for that kind of reflection than the Memorial and Museum."
