For almost 20 years, families have memorialized the victims of the 2001 and 1993 attacks on the World Trade Center by reading aloud the names of those killed.

But this year, due to concerns about COVID-19, the on-site ceremony organized by the National September 11 Memorial and Museum will instead air a pre-recorded reading over speakers. A separate ceremony organized by the Tunnels to Towers Foundation will continue the tradition of reading the names live, just a few blocks away at Zuccotti Park.

Both memorials will only allow family members to attend in-person, though the museum's will be streamed online.
