Experiencing Memory: Designers Reflect on the 9/11 Memorial Museum

Trident columns recovered from the World Trade Center stand in Snøhetta’s entry for the 9/11 Memorial Museum, otherwise designed by Davis Brody Bond. The pavilion is flanked by the twin pools of the memorial, completed by Michael Arad with the firm now known as PWP Landscape Architecture, and surrounded by the towers of the financial district.

A gallery’s interactive tables allow visitors to pull up additional information about the victims pictured on the screens. Photography by Jin Lee.

Allowing the outlines of box columns to remain untouched, per the wishes of victims’ families, bridges give access to two galleries. Photography by Eric Laignel.
