A key feature of downtown Baltimore’s World Trade Center plaza, this memorial honors the 63 Marylanders who lost their lives on September 11, 2001. The inspiration for the memorial, a 22-foot-long steel artifact consisting of three twisted and torn steel columns, is drawn from the wreckage of the Twin Towers.

The memorial also represents the other two 9/11 sites: Limestone pieces from the Pentagon’s west wall are integrated into the design, and though artifacts cannot be obtained from the Flight 93 site, it is represented with three large pieces of polished black granite.

Silman provided structural engineering services for the design and construction of the new memorial. Due to the immense weight of the artifacts that comprise the memorial – the entire section weighs approximately 5,000 pounds – Silman designed extra structural support to compensate for a 30-foot-wide tunnel running under part of the plaza. This entailed balancing the concrete plinth on two points that coincide with two of the existing plaza columns below.

The marble plinth acts as a sundial on the plaza, marking the passage of time as the morning sun crosses the sky and creating a shadow from Baltimore’s World Trade Center that intersects with the memorial. A portion of the marble plinth always remains in sunlight.
