ABOUT THE WTC LOGO The upper 'bars' of the logo represent a stylized W — for World Trade Center. The slope across the upper bars is at a 17.76-degree angle, reflecting the height of 1 World Trade Center. The two parallel spaces in the upper half of the logo are intended to evoke the memorial beacons of the Tribute in Light. http://www.mas.org/programs/tributeinlight/ The two bars on the lower half of the logo represent the deep pools of the National September 11 Memorial. http://www.911memorial.org/memorial
