Assignment Baghdad

[Image: Screen-grab from a YouTube compilation of Desert Storm missile strikes].

In the summer of 2016, I heard an incredible story from a retired Defense Intelligence Agency analyst. It combined architectural history, international espionage, an alleged graduate research seminar in Washington D.C., and the first Gulf War. I was hooked.

According to this story, a graduate class at a school somewhere in D.C. had set out to collect as much architectural information as it could about Saddam Hussein’s Iraq. This meant, at one point, even flying to Europe on a group field trip to visit engineering firms that had done work for Saddam Hussein.

Given the atmosphere at the time, the students most likely thought that their class was an act of protest, a kind of anti-war gesture, meant to help record, document, and even preserve Iraqi architecture before it was destroyed by the U.S. invasion.

Ironically, though, unbeknownst to those students—possibly even to their professor—the seminar’s research was being used to help target U.S. smart bombs. Or, as I phrase this in a new article for The Daily Beast, “there was a reason U.S. forces could put a missile through a window in Baghdad: they knew exactly where the window was. Architecture students in Washington D.C. had unwittingly helped them target it.”

But then things got complicated.

When I called my source back a few weeks later to follow up, it felt like a scene from a spy film: he said he didn’t remember telling me this (!) before joking that he was getting old and maybe saying things he shouldn’t have. This obviously only made me more determined to find out more.

I called every major school in Washington D.C. I FOIA’d the CIA. I started down a series of rabbit holes that led me from true stories of Gulf War espionage, involving U.S. attempts to collect blueprints for Saddam’s bunkers from engineering firms all over Europe, to a conversation with the head of targeting for the entire U.S. Air Force during Operation Desert Storm.

Along the way, I also kept finding more and more examples of architects and espionage, from Baron Robert Baden-Powell’s incredible use of butterfly sketches to hide floor plans of enemy forts to a 16th-century Italian garden designer who was, most likely, a spy.

Even Michelangelo gets involved, as his designs for urban fortifications outside Florence, Italy, were secretly modeled in cork and snuck out of the city by an architect named Niccolò di Raffaello dei Pericoli—or Tribolo—in order to help plan a more effective siege (an anecdote I have written about here before).

In any case, I was sitting on this story for the past two years, waiting for my FOIA request to come back from the CIA and trying to set up interviews with people who might have known, first-hand, what I was asking about. The resulting article, my attempt to track down whether such a class took place, is finally up over at The Daily Beast. If any of the above sounds interesting, please click through to check it out.

Finally, of course, if this rings any bells with you—if you took a class like this and, in retrospect, now have doubts about its real purpose—please be in touch.

Governor General of Fortifications

As part of some tangential research for an article of mine coming out this weekend, I found myself looking at Michelangelo’s incredible sketches for fortifications and defensive works designed for the city of Florence.

Michelangelo served as “Governor General of Fortifications” for this massive military project, undertaken in the late 1520s to protect the city from an eventual 11-month siege.

While Michelangelo’s walls play only the most marginal role in the actual article I was writing, I was so taken by the images that I thought I’d post a few here. Graphically bold and interestingly layered with other sketches and drawings, they’re surprisingly beautiful.

Indeed, as the late Lebbeus Woods wrote, “For all their practical purpose, these drawings have uncommon aesthetic power.”

[Image: Michelangelo’s sketches for the fortification of Florence].

This wouldn’t be surprising. In a paper called “‘Dal disegno allo spazio’: Michelangelo’s Drawings for the Fortifications of Florence,” historian William E. Wallace points out that, “In the Renaissance, military engineering was an important aspect of the profession of being an artist.”

Designing defensive works to protect his own city from attack was thus a natural continuation of Michelangelo’s expertise, and his artistic sensibility only made the resulting designs that much more visually captivating.

[Image: Michelangelo’s sketches for the fortification of Florence].

The vocabulary for these structures is also, in its own way, strangely mesmerizing.

As Wallace writes, for example, this is “a design for an extremely complex detached bastion, a triangular-shaped defensive work usually projecting from a rampart or curtain wall, but here situated in front of a rectangular city gate which is drawn toward the bottom center of the sheet. The fortification is actually composed of three separate outworks or lunettes, and two ravelins, the long narrow constructions placed in front of the defensive work in order to break up a frontal assault. The various parts of the fortification are linked by removable log or plank bridges, and the whole complex is surrounded by a ditch repeatedly labeled ‘fosso,’ the outer rim of which, the counterscarp, has a stellate outline echoing the pincerlike (tenaille) form of the fortification.”

Bastions, counterscarps, outworks, lunettes. Ramparts, ravelins, stellate outlines.

In any case, you can see more over at Lebbeus Woods’s site, or in Carmen C. Bambach’s gorgeously produced exhibition catalog, Michelangelo: Divine Draftsman and Designer.

The city and its citadels

While writing the previous post and looking for a link to FSG, Robin Sloan’s publisher, a fortuitous auto-fill in my browser bar led me to the Fortress Study Group, the “international society of artillery fortification and military architecture.” Their site includes a helpful series of PDFs on the architectural history of fortification, or “the development of fortifications designed to resist artillery,” including this long look back at the group’s most recent “study tour” (similar in many ways to the Fortifications Tour we explored on BLDGBLOG long ago).

Of particular note: through their site, we learn that a symposium called Fortifications at Risk 2 will be held in March 2013 at the National Army Museum in London, discussing “how derelict fortifications may be preserved and re-used” for future purposes. You can register here.

Briefly, I’m reminded of historian Steven Jaffe’s fascinating book, New York at War: Four Centuries of Combat, Fear, and Intrigue in Gotham, in which Jaffe details the construction of coastal forts and artillery batteries throughout New York City, from colonial times to the Civil War (and beyond).

In particular, Jaffe cites the work of inaugural West Point superintendent Jonathan Williams, “mastermind of New York’s harbor fortifications,” in Jaffe’s words, who designed and proposed “a network of new fortifications placed strategically” at the marine entrances to the city during the War of 1812. His designs included “stone and mortar citadels” peppering the shores and “a line of massive stone blocks” that would be dropped into the harbor waters, forming a kind of submerged gate topped with barrier chains and artillery, further closed in places by the hulls of deliberately scuttled ships, seemingly an architecture equal parts wreckage and military geometry.

The majority of Williams’s defensive plan was never built; however, Castle Williams on Governors Island, which we boated past last week as part of Dredgefest 2012, is still there in its circular ruin, not far from the massive unmarked ventilation structure for the Brooklyn-Battery Tunnel which roars beneath the harbor waters.

An unbuilt fortifications tour of New York City is thus quite an interesting prospect.

The Baffler

In a paper called “Baffles and Bastions,” published in the Journal of Archaeological Research, anthropologists Lawrence H. Keeley, Marisa Fontana, and Russell Quick offer a detailed history of militarized building design features such as “V-sectioned ditches, defended gates, and bastions.”

All of the features they subsequently analyze occur at peripheries, borders, and thresholds. In their own words, “the militarily functional ditch and gate features and bastions discussed below, in fact and by definition, are all distinguished by being part of enceintes (that is, surrounding barriers or enclosures). Enceintes are barriers that prevent access to and, almost always, obscure vision of a particular location.”

Their diagrams of “baffled” entryways, seen above, are particularly interesting—a kind of archaeological variation on floor plan porn—revealing the various techniques used to at fortified points of entry to gain an advantage over invaders. Through a navigational encounter with architecture, attackers are forced to show their vulnerabilities. “Baffled gates force attackers who enter them to expose their flanks and rear to defenders’ fire,” the authors write. “Ideally, they require attackers to turn left exposing their unshielded right side. Left-turning baffles also were useful against (typically) right-handed bowmen.”

Maunsell Towers

I missed an amazing opportunity the other week to visit the Maunsell Towers – aka the Maunsell Sea Forts – with Nick Sowers, author of an excellent Archinect school blog and one of my students from this summer’s studio down on Cockatoo Island in Sydney.

For the last year or so, Nick has been traveling around the world on a much-deserved John K. Branner Fellowship, documenting army bases, abandoned bunkers, and other sites of historical military interest. From South Korea to the Maginot Line, from classical war zones and medieval walled cities to “bunker recycling services” and D-Day, Nick’s itinerary is breath-taking. It is also, I hope, intriguing enough to catch the eye of future publishers or gallerists who might want to give Nick the space in which to break down all that he’s seen; there are very many of us who would love to learn more.

Of course, we could also hear more about his trip: Nick is acoustically-inclined, and he has been documenting the sounds of these militarized landscapes over on another blog he runs, called Soundscrapers.

So Nick and his wife were in England the other week, and we unfortunately missed meeting up – but they managed to take a boat tour out to the Maunsell Sea Forts, iconic architectural structures in the Thames Estuary, inspirations for Archigram, and one of the few real-life buildings (if you can call them that) that gave me the idea to start BLDGBLOG. In fact, I’ve mentioned these places in lectures and I’ve posted about them on the blog before – but I’ve never had a chance to visit.

Nick’s photos, presented here, alongside photos by Pete Speller, will tell the story instead.

As Underground Kent explains, “The Thames Estuary Army Forts were constructed in 1942 to a design by Guy Maunsell.”

Their purpose was to provide anti-aircraft fire within the Thames Estuary area. Each fort consisted of a group of seven towers with a walkway connecting them all to the central control tower. The fort, when viewed as a whole, comprised one Bofors tower, a control tower, four gun towers and a searchlight tower. They were arranged in a very specific way, with the control tower at the centre, the Bofors and gun towers arranged in a semi-circular fashion around it and the searchlight tower positioned further away, but still linked directly to the control tower via a walkway. All the forts followed this plan and, in order of grounding, were called the Nore Army Fort, the Red Sands Army Fort and finally the Shivering Sands Army Fort. All three forts were in place by late 1943, but Nore is no longer standing. Construction of the towers was relatively quick, and they were easily floated out to sea and grounded in water no more than 30m (100ft) deep.

They thus entered into the imaginations of speculative architects everywhere; they helped give visual shape to Archigram’s Walking City; and they continue to offer a kind of real-life spatial analogue for Constant’s New Babylon for anyone with access to a boat.

Nick explained in an email that he visited the structures with Tony Pine, a “sound engineer” – i.e. pirate radio operator – who spent the afternoon “telling stories of the days in the 60s when Archigram came out to visit the structures, and also about incredibly cold winters when they burned the wood-fibre linings of the tower interiors to stay warm.”

Also along for the ride was Robin Adcroft, director of Project Redsand, who “describes himself as the caretaker of the structures.” Adcroft points out the genealogical importance of these structures:

The Thames Sea Forts are the last in a long history of British Marine Defences. The Army Anti Aircraft forts have played a significant role in post World War 2 developments. Notably in offshore fuel exploration and drilling platforms. The successful rapid deployment of the Maunsell Forts soon after led to the construction of the first offshore oil platform in the Gulf of Mexico in the late 1940s.

Both conceptually and materially, the Maunsell Towers have an architectural legacy that seems oddly under-explored.

But “it’s interesting,” Nick adds: “no one actually owns these things.”

Apparently the transport authority wanted to give Project Redsand a deed but they declined it, not wanting the liability. A ship crashed into Shivering Sand (an outpost which is visible from Redsand) in the 60s, taking out one of the towers and killing two maintenance personnel. Red Sand is not actually in the shipping lane, but it is very much a hazard. The original 1/4 inch plate steel is rusting through to a paper thickness. We had to wear hardhats when the boat pulled in next to the structures.

Project Redsand has more information about efforts to preserve the forts – and they link to this short YouTube video in which you can see how these clustered towers might be stabilized and maintained for generations to come.
