    Why the 9/11 Memorial and Museum is worth it

    The attacks of that day killed 2,977 people, here, at the Pentagon and in a field in Pennsylvania. The memorial is for them and for the six who died when the World Trade Center was bombed in 1993. The architect Michael Arad won the competition for its design and worked on it with the landscape architect Peter Walker. It was dedicated on the tenth anniversary, 11 September 2011, and opened to the public the next day.

    It is two square pools, each sunk into the outline of one tower, with water falling down all four sides and then again into a smaller square at the centre whose bottom you cannot see. The names of the dead are cut through bronze panels round the edges. Around the pools is a grove of swamp white oaks.

    The museum opened in May 2014 and lies under the plaza, at the level of the towers' foundations. It tells the day hour by hour, with what was found afterwards: crushed fire engines, a staircase people escaped down, the last steel column taken from the site.

    What to see

    1. The two pools

      Walk round both. The names are grouped by where people were and whom they were with: the crews and passengers of each flight, the firefighters of each company, colleagues side by side.

    2. The Survivor Tree

      A Callery pear found burnt and broken in the rubble, nursed back in a city nursery and replanted on the plaza. It is the tree with the supports, and it flowers first in spring.

    3. The Survivors' Stairs

      Inside the museum, the flight of outdoor steps down which hundreds of people fled the plaza that morning. It was the first object brought into the building.

    4. The Last Column

      The last piece of steel to leave Ground Zero, in May 2002, covered in the messages and photographs that recovery workers fixed to it. It stands in the great hall at the bottom of the museum.

    How to do it well

    • The memorial plaza is free and needs no ticket. The museum is ticketed and entry is at a set time: book ahead.
    • Allow at least two hours for the museum. The historical exhibition at its centre is long and is not suited to young children.
    • A white rose placed in a name on the pool marks that person's birthday. The staff put them there each morning.
    • One World Observatory is in the tower beside the plaza and can be done on the same visit.
    • It is a place of mourning for many of the people around you. Do not sit on the name panels.
