At the age of thirty-four, the Israeli-born architect Michael Arad won the World Trade Center Site Memorial Competition with his submission, “Reflecting Absence.” He spoke with Habitus editor Joshua Ellison as the site was readied for its unveiling on September 11th, 2011.
You are an immigrant to New York but you have now made an imprint on the city that few people could equal. How has this process changed your relationship to the city?
I think what really changed my relationship to the city came before this project—the 9/11 attacks and the response of New Yorkers on that day. I’d been living in New York for close to three years. I’d lived here before at a much earlier age, in sixth grade. I had come and gone from New York throughout college and graduate school, but I felt very much like an outsider here. It was a city that always intrigued me; I knew I wanted to come work here and live here. But even after being here for a number of years, I still felt like an outsider—I think New York is a city that’s full of outsiders.

Arad, the architect/designer of the World Trade Center Memorial
Having an Israeli background, New York was far removed from the difficulties of living in Israel. Back home, I knew that prevalent sense of vulnerability—violence could be waiting on the next bus ride or around on the next corner. When the 9/11 attacks happened, that misplaced sense of security evaporated in an instant.
But I also gained something: All of a sudden, by going through the crucible of this experience, I felt a tremendous sense of kinship to my fellow New Yorkers. All my neighbors, the people I saw on the subway, the people I saw on the street, and the people I saw gathering in public spaces like Union Square and Washington Square: we were one. That was very powerful and moving. In particular, I recall going to Washington Square a couple of days after the attacks—I was living in the East Village at the time—and our neighborhood, like everything south of Fourteenth Street, was shut off from the rest of the city. There were no cars, hardly any people outside. I went for a bike ride in the middle of the night—two, three in the morning—in an ever-widening circle, starting in my neighborhood, making my way over to Chinatown and TriBeCa and the West Village. I eventually ended up in Washington Square Park and I walked up to the fountain. There were candles surrounding the fountain and there were people standing there. I think people came there the same way that I did, alone or maybe with one other friend, but people stood there together. And when I walked up to that fountain, that circular fountain, I joined that circle of people and I didn’t feel alone anymore. I don’t think I understood the significance of that moment, but in many ways it was a very transformative moment for me: I felt that I became a New Yorker, realizing that this is my home.
One of the interesting tensions around this memorial project has been the question: Is this a national memorial or a New York City memorial?
It’s a national memorial. I think that’s how everybody involved in it right now sees it. At some points over the last few years, there were questions about whether or not we should include the names of people who died in Pennsylvania, or in Washington, or Virginia. For me, it was never a question.
I also think it goes beyond being a national memorial; I think it’s part of our shared human heritage, wherever we are coming from. There are people from over sixty countries among the victims. And New York is an incredibly cosmopolitan city that brings people in from everywhere and gives everybody a shot—I’m not going to say an equal and fair shot, but it gives everybody opportunities which they might not have elsewhere.
You have written that you started thinking about memorial ideas very shortly after the event.
We were living next door to a pastry shop called De Robertis on First Avenue, between 10th and 11th, and shortly after the attack, they put up a cake in the window that had an image of the Twin Towers. It said, “We will never forget,” in frosting. When I first saw it, I thought it was in terrible taste. But as I walked by it, day after day, I grew to really appreciate the gesture. These people used their best means of self-expression. They wanted to find a way to express themselves and they used the tools that were available. It was easy to be very dismissive of that when you first saw it. But I came to realize it was not that dissimilar to what I did when I started to sketch ideas on a piece of yellow tracing paper. I was trying to find a way to make sense, to acknowledge what we had seen, what we had suffered. I spent close to a year on what was a very personal and very cathartic exercise of exploring these ideas. There was no memorial competition, there was no client driving the design project. This was a very personal effort, something I spent days obsessing over and building and sketching and designing.
You originally envisioned a memorial on the Hudson River.
It was the image of the river being torn open, and I imagined walking up to the edge of the river and looking beyond, and feeling this sense that the fabric of space had somehow been torn open and water was falling into these voids—and that these voids would never be filled. It was a completely enigmatic and inexplicable image, and I spent a lot of time trying to realize it. I wasn’t sure if it could be realized.
I built a little fountain in a miniature scale—twelve inches by twelve inches. A year later, there was a competition for the design of the memorial. I wanted to see if I could take those ideas that I had for the voids on the Hudson and in some way reinterpret them. I also wanted to bring that sense of creating a specific place—a place of assembly within the city, like Union Square, like Washington Square—that helped me confront that day, not alone but as part of a project.
In both the Hudson design and the competition version, you started with the idea of submerged forms or negative spaces.
It was about creating a space that would remain inaccessible and empty, an emptiness that I think is filled with meaning. I was making the absence visible—something that is not erased with the passage of time.

The void doesn’t really open up under you until you’re right there, right at its edge. It’s a very visceral reaction: you really feel it in your chest, in your gut, as you walk up to them.
This idea of “reflecting absence” seems to repeat a question that has been central to memorial design since the Second World War, which is: How do you capture in physical space the enormity of a tragedy that is beyond measure? Did you look to other memorial projects for guidance?
As an architect, I’ve seen many memorials and many buildings and many monuments, so all of those feed into the design unconscious. You don’t know where everything that you draw upon and think of comes from. It comes from a mixture that is deep within.
On the question of memorializing, one of the difficulties here was that the number of deaths—close to 3,000—could easily become an abstraction, a number that’s impossible to grapple with and understand and break down. We arranged the names of the victims around two pools according to meaningful adjacencies. The idea was that there would be a reason why one name is close to another name, that these adjacencies and the placements of the names would reflect the relationships that existed between the victims. A lot of the victims knew each other very well: they’d worked together, some of them were families that died together, some of them commuted together every morning, or went to school together. Some of them only got to know each other that day. In their effort to help each other, some of them died together. I wanted to reach out to family members and ask them if there were names of other victims that they would like to see next to the name of the person they lost. This was a big “ask,” so to speak, for the memorial foundation. This was something I’m still surprised we were given the opportunity to do, because it was a tremendous risk, and institutions and the people who run institutions are usually risk averse.
Mayor Bloomberg deserves tremendous credit for giving us the opportunity to pursue this. It wasn’t until 2006, when he became chairman of the foundation, that we were given a green light to go ahead and try this. And then it wasn’t until 2009 that letters finally went out to family members asking for this input. We got over 1,200 requests from family members, and we spent a year arranging the names very carefully to meet each and every request. It was a very emotionally challenging task—it was the kind of task where you had to hold onto that depth of feeling without letting it overwhelm you, and without becoming callous to it either. There are incredibly sad stories that are now embedded in the very fabric of this memorial design. These relationships, to the naked eye, are invisible: it looks like a random array of names, but in fact there are constellations of adjacencies.
There’s one particular story of a meaningful adjacency that I’ve shared a number of times. Abigail Ross Goodman lost her father that day. He was on Flight 11. She lost her best friend, Stacey Leigh Sanders, too, who was working in the North Tower. Flight 11 crashed into the North Tower, and so she lost her father and her best friend in an instant. We got a request to put those two names side by side, and initially we didn’t know why. You find out one story after another. I don’t know all the stories that are part of these arrangements—I don’t think anybody will ever know all the stories.
However you come to know them, I think there are ways to transmit these incredibly sad and moving stories and to build up a sense of understanding, one person at a time, adjacency by adjacency. This way, we might better understand what happened that day, rather than become confounded by the close to 3,000 deaths. I think these individual stories will always have resonance. There will be new ways to share these stories that I can’t imagine yet, but someone else will become involved in doing this. The meaningful adjacencies are a way for us to address that question that you are asking about: how do you memorialize, especially when it seems like such an overwhelming task, something that is beyond comprehension?
It also strikes me, as an architectural matter, that the use of the names is an interesting response to one of the major challenges of the site, which is the enormity of the scale of the space. It is a way of allowing for a more intimate, quiet register within this really vast expanse.
In some ways, these design decisions were very straightforward. We knew we wanted to place these pools where the towers once were. We knew we wanted their scale to be commensurate with the size of the towers’ footprint and we knew that we wanted every name listed. After that, it was about letting the history of the site come forward through these design elements. When you have very clear objectives, it becomes easier to make decisions that are going to be consistent.
You are also very conscious, programmatically, of how a viewer moves through the space. Can you talk a little bit how you envision that?
Well, I think the experience of the memorial actually begins when you consider the scale of this neighborhood. If you think of Lower Manhattan, of these tall and narrow urban canyons where you can barely see a sliver of sky in some instances, and you walk out of these canyons onto this vast, open plain—this eight-acre memorial site—where a clear dome of the sky is so present all of a sudden: You are at once within the city and also looking at it as if you were outside it. You have this distance that separates you from Lower Manhattan even though you are firmly within it.
For me, it was always about rooting the site back into the life of the neighborhood, and also giving you the opportunity to separate yourself from everyday New York life. It’s a very dynamic relationship, I think, between the site and the surrounding city. The site is very much defined by the buildings that will rise around it. I think it’s powerful, once you cross the street and step onto the memorial plaza. You discover this unexpected forest of nearly 400 trees. You walk under their canopy and the view of the city becomes even more mediated through that permeable ceiling of branches and leaves. Then you walk deeper into the site, to the edge of one of two enormous voids.
We designed these voids with an eight-foot wide and two-foot tall water table that surrounds them and serves as the spring point for the waterfall. Above that, there are the bronze panels where the names are inscribed. What happens is that you can start to see the scale of the void—you start to see the waterfall from 200 feet away—but the void doesn’t really open up under you until you’re right there, right at its edge. It’s a very visceral reaction: you really feel it in your chest, in your gut, as you walk up to them. It’s the kind of thing that you can’t really capture in a photograph because a photograph isolates the sentiment into something that is just a visual image. But when you’re there, your sense of balance is upended by what is around you. And then, as you stand there at the edge of void, and as you take in this enormous space, you see this multitude of names that surrounds each pool—close to 1,500 names over each void.
You start walking slowly and gradually around these pools, taking in one name after another. Each name has a geographic component to it that I think is very important, and it’s reinforced by these meaningful adjacencies, though you might not know about them. When you walk up to the void, what you see is one name and then another and another and, together, they coalesce to form a river of names that surrounds each pool. But each name is an island unto itself. What is on this memorial is the name of the person—that most essential marker of the unique identity of the individual—and, at the same time, there’s also this assembly of names, all together. I think it was important to me to draw on the individual loss, but also this collective loss that we suffered—that sense of the individual and the universal.
There have been commemorations of 9/11 at every scale, from the very personal to the civic and political. You talked about your neighbor’s bakery. So why is it important to have an official response, a single space that focuses all this memory and mourning?
I don’t think it’s a single response, I think it’s one of many responses. This is the “national” 9/11 memorial and it has a standing that is separate from those others, as an institution of the state. I think that’s appropriate, but I also think that it does not thereby give it more meaning or a better meaning than other memorials that reflect the diversity of responses that we had to that day. There should be multiple ways of understanding that event, and I think there will be multiple ways of understanding this memorial. I think many people will walk away from it with very different understandings and resolve to respond to what they have seen in very different ways.
You mentioned before that Israel was your family home. I wonder if you feel like you have internalized anything about that country’s approach to memory or memorialization in the way that you approached this design.
I don’t necessarily think so. I was born in London, I grew up in London and New York and Washington and Jerusalem and Mexico City, and that was all by the time I graduated high school. So I think that all of these influences are part of it, so maybe no is the wrong answer—the answer is yes and…
Was I influenced by the military cemetery in Jerusalem? Yes, but I was also influenced by seeing Chichen Itza and the pyramids in Mexico. One of the benefits of having a childhood that was spread across so many continents is that you start to see the universal in this world and understand that there is much more that unifies us than divides us. When it comes to something as difficult as dealing with death, you will find that to be more the case than anything else.
Memorials necessarily have to address themselves to posterity. I wonder if you have given much thought to what someone in the future will learn about what happened on 9/11 from visiting your memorial—is it meant to be educational in that sense?
That moment that I described to you earlier of walking up to the edge of the void and seeing the scale of this space, which echoes the scale of the towers’ footprints, and seeing the multitude of names that surrounds each void—that is an incredibly powerful moment. It is the moment of walking up to a threshold, to this line that separates the living from the dead. I think this will always be a powerful moment. Fifty years from now, a hundred years from now, even when people might not know every detail of that day, they will still comprehend in an instant that this happened.
I think that’s important. But I also think this story is going to be told in many other venues. When you built a memorial a thousand years ago, it was in the absence of the printing press, the Internet and movies and every other medium that we now have at our disposal to share information, to disseminate information, and to connect to people. So this idea that the memorial is somehow singlehandedly going to convey the story of 9/11 to future generations—that’s not going to be the case. I am not trying to get myself off the hook. It does need to do something very profound. But it’s part of a much larger combination of forces, and if you looked in the paper on almost any day in the last ten years, there would have been some reference to some aspect of 9/11. Whether it was a story about security at airports or immigration or the wars or anything else, it is all part of that story. I think we’ll be discussing 9/11 for a long time to come.
That must be liberating as a designer, in some sense.
It allowed me to focus on what I thought was most essential. I don’t think I could ever have become of the sole arbiter of the meaning of 9/11. Anybody who thinks they can has a very narrow agenda.
