Set to open to the public on Wednesday after a highly controversial and contested journey from idea to reality, the September 11 Memorial Museum has inevitably been a talking point among critics this week. The museum by Davis Brody Bond occupies the space between the Memorial Plaza at ground level and the bedrock below, with an angular glass pavilion by Snøhetta providing an entrance from above. A long ramp, designed to recall the access ramp with which tons of twisted metal was excavated from the site, descends to the exhibits which sit within the perimeter boundaries of the twin towers' foundations, underneath the suspended volumes of Michael Arad's memorial fountains.

The content of the museum is obviously fraught with painful memories, and the entrance pavilion occupies a privileged position as the only surface level structure ground zero, in opposition to the great voids of the memorial itself. The discussion at the opening of the museum was therefore always going to center on whether the design of the museum - both its built form and the exhibitions contained - were sensitive and appropriate enough for this challenging brief. Read the critics' takes on the results after the break.
