 On March 9, 2008, the Staircase was moved by crane about 200 feet on Vesey Street.In 2010, as construction throughout the World Trade complex reached peak activity level, the staircase – as well as two "tridents" of Twin Tower facade, and other oversize artifacts – was placed into the National September 11 Memorial & Museum space before the Memorial Plaza and museum entrance pavilion were built above it.The staircase is now a major feature of the museum.
