The memory of 9/11

Do not often visit the place and feel powerless in front of something inexplicable and emotionally impactful . In the " National 9/11 memorial" , this feeling makes almost uncomfortable. Too loud what has happened here and just as emotionally beautiful, the ugly of what happened, what has been achieved. The World Trade Center still exists, despite the absence of heavy twin towers. To remind you there are two waterfalls of nine meters , sinking up to not being able to perceive the end . Their perimeter is surrounded by bronze parapets and above , are engraved the names of the nearly three thousand victims of the attacks of those days , including firefighters and police . Why everyone can share the emotions flow from being in that place, there is a garden : short 'll be completed and will be open , with no more checks at the entrance .

Objectives and memory. The project , called " Reflecting Absence " is the landscape architect Peter Arad and Peter Walker of the study and was selected in a contest that had over 5000 participants . There are many pressures and protests coming from politicians and families of the victims that have changed , in part, the contents . The initial objectives , however, remained intact and walking in the park they all feel . The idea , in fact, was to create a large void where the towers were , to achieve a contemplative place ( the waterfalls are also able to cover the noise of the city) and give the public a new place in Manhattan where you can stop . To finance it all there is a foundation ( National September 11 Memorial & Museum Foundation) that gesrtisce manage the funds to complete the memorial.

The project of the Memorial.  

Trees and lawn. If it seems to be in and out of the city at the same time, it is about the 412 white oak (Quercus bicolor) and dial choices to complete the memorial . Planted as adults and perfectly formed , the trees are arranged in rows interspersed with lawns and benches where visitors can stay . The arrangement of the oak is not random, because it recalls the arches at the base of the twin towers . To underline the choice of species , carried out years before planting , so that the nursery had time to cultivate it for five years in large containers , according to the request of the designer. Scaffolding, trunk diameter and height are standardized and conform to the idea of creating sturdy columns and a foliage canopy , able to cover the entire floor area . Even the flooring has been designed to avoid the causes of stress in plants in urban environment . The sheets on which people walk , in fact, are laid down on a layer of soil not compact and rainwater is drained and fed in large tanks for reuse . The rusticity of Quercus bicolor, species native to the mid-west and south of New -England , ensuring the adaptation and persistence of the grove in the city.

The Tree of survival. There is only one plant that is different from all the others. It is not an oak tree , but a Pyrus calleryana and takes on a symbolic value : it is the only tree survived since 2001, and after the removal of " ground zero " , appeared seriously compromised . It was decided to uproot and transfer it into a park in the Bronx where he was revived . The past year has been replanted in its original place becoming a real added value. And it has become a monument to survival.


Where were the Twin Towers now there are two large waterfalls and a park with over four hundred trees. The memories of that tragedy have become landscape
