The Bank Tower at Oak Cliff’s annual 9/11 commemoration normally begins and ends the morning of Sept. 11. But this year, the remembrance will last 10 days.

The building’s managing partner, Ralph Isenberg, who collects 9/11-related art, has installed clear acrylic likenesses of the Twin Towers in the building’s lobby. One measures 48 inches tall and represents the south tower. The other is 59 inches tall and represents the north tower and its radio antenna.

They sit on acrylic bases that represent the underground portion of the World Trade Center.

Starting today, Dallas fire fighters will drop by intermittently to read the names of the 421 first responders killed on 9/11. After each name is read, they will drop a piece of paper with the person’s name and a small block into the base of the sculpture.

Starting next week, Isenberg has asked neighbors to stop by the building’s lobby to begin reading the names of the civilians who were killed. Their names and a colored block will be dropped into the part of the sculptures that represent the towers. Anyone is welcome to participate in the civilian roll call. Isenberg has invited students from four Oak Cliff schools, which will take field trips to participate in the installation.

“It’s really important to get them involved because it’s been nine years, and some of these kids weren’t even born yet,” Isenberg says.

The ceremonial commemoration will be on Friday, Sept. 10 at 8:30 a.m. The Sunset High School ROTC will do the flag ceremony and lead the pledge of allegiance.

Two yellow flags will be raised, across Zang Blvd., and a bagpiper will play.

Bank of America, the building’s groundfloor tenant, is providing docents for the art installation. Isenberg’s 9/11-related art collection is on display in the building’s lobby, and it includes pieces that have not been shown before.

The acrylic twin tower sculptures were designed by Isenberg, Tim Alonzo of Isenberg Management and Ken Demko of Demko Construction.
