Istanbul 4 - Theodosius Jumps

HARBOR WALL: SITE

The urban renewal in the 1980's that exposed the harbor wall also

created a park where there once was a crowded fishing and maritime

industry. Preservationists decried this sterilization for tearing down

more than a few treasures that stood in the way, although there are a

handful of historic structures trapped in peculiar traffic islands.

Over the past 20 years there has been an admirable effort to clean the

Golden Horn, so that today it is common to see people swimming and

fishing in it. It no longer has the stench of pollution, and is seen

again as an amenity, this time for recreation instead of industry. It

is a common story around the world, and as the water again gains in

popularity, so does the park. People arrive early on the weekends to

stake a claim, and those who arrive later are relegated to the zone by

the street. The waterfront and roadfront are two different worlds,

though due to the demand, both are filled.

The park is heavily used by families picnicking, but the traffic is

bad. It is dirty and noisy, and creates a modern wall of noise and

danger that separates the neighborhood from the waterfront and

impinges upon their recreation. Often illegally parked cars provide

the only filter between the activities and the high speed roadway. The

noise is intense and the grilled food acquires the unfortunate flavor

of road pollution. Today's marauding hordes are buses and taxis.

HARBOR WALL: THE RECYCLED CITY

The old city walls present an alternative, possibly heterodox, version

of preservation. It is often stated that Istanbul is a city of layers,

but more precisely, it is a city of layered conquest. There have been

many distinct masters of the city, and each time the city was reborn

in the image of the conqueror.

Byzas....Constantine...Justinian...Theodosius...Mehmet...Ataturk...Dal

an...Topbas...at each transition, the contested city became an urban

canvas on which the projections of the new authority were writ. The

Byzantine Milion (the Golden Milestone) was disassembled to construct

a nearby water tower. The Roman Basilica Cistern is supported by 336

columns taken from the extent of the empire; S�leyman took the top

tier from the hippodrome and used it in part to support his mosque

complex.

No where is this recycling more evident than in the city walls.

Looking closely at the walls you will see column pieces, entablature,

gravestones, steps and other miscellany of the past. It is a masonry

soup of losers; civilizations consigned not to the trash heap of

history, but the recycling bin. There was also a practical reason for

the layering of disparate materials: the diverse material properties

would react to earthquakes differently and make the wall less likely

to fail catastrophically. Great works that once indicated wealth and

power in turn made ample filler. The first line of defense was

comprised of the cultural oeuvre of the previous empire.

HARBOR WALL: THEODOSIUS JUMPS

I propose a recycled and repositioned harbor wall, fortifying the park

against the proximate undesirable vehicles. But more than a wall, it

would be a repository for all the fast diminishing cultural artifacts

in the city. Over time it would increase at the pace of the renewal of

the city. As historic structures are disassembled, they would be added

to the new wall in discreet segments approximately half a meter high.

Each segment would represent one "lost" project recycled back into a

new use. The segments would march along the park where they are

needed, and leapfrog over defined thresholds and areas where the park

is not used for recreation. After the approximately two kilometers of

park is lined, a second layer would begin snaking back to the

beginning. Instead of the current condition of tertiary heritage being

simply thrown out or lost as aggregate in new projects, the new park

wall would be a zone of collection and growth. Thus the wall would

mature, acting as a barometer of urban renewal. The taller the wall,

the more things lost, the more progress gained.

At the same time, recreation in the park would be protected from the

traffic on Abd�lezel Pasa Avenue on the other side of the wall. At

first it would simply act as a line of definition, but in time would

grow above the height of cars and tour buses. Grilled meat wouldn't

taste like exhaust anymore. Children would kick balls against the

wall, perhaps hitting a Byzantine relief. People would lean against

Roman bricks and columns. Thresholds in the wall would accommodate

sidewalks and the few building uses, and in places where the park is

too thin to be usable, the wall would disappear, giving the drivers a

periodic view of the Golden Horn. Because each segment would be a
