Transgression/Transition: an exploration of the Senne and its surroundings

Transgression/Transition, an exploration of the Zenne and its
is an ongoing research project on the Belgian Zenne river.
The project started in April 2015 and has known several moments of
exploration and presentation since. In August 2015, as part of the project,
I initiated a field research along the Zenne by walking the 103 km course of
the river.

The Zenne has its source in Soignies (Wallonia) and flows into the river of the Dijle at Heffen (Flanders) from where it finally reaches the Schelde and the North Sea. The Zenne flows through the three Belgian regions -Wallonia,
Brussels Capital Region and Flanders- and passes the city of Brussels and
some thirty villages. The river has no existing trail that follows its course. At
certain points it flows underground or along private property.

Even though the Zenne is a small and unnavigable river, it has had a very
eventful history. It is an undervalued river, much maligned and rather tucked away than seen. For centuries, the Zenne has been used as an open sewer where not only the excrement and waste water of thousands of families flowed away, but also heavy chemicals from adjacent factories.

In the nineteenth century, the city of Brussels recognized that the Zenne as
open sewer increasingly endangered public health. The water was
contaminated and because of regular flooding epidemics were easily spread. In 1867 large-scale activities started to fully canalize and tube the Zenne in the center of Brussels. On the ensuing north-south axis, Parisian-style avenues were constructed: the Boulevard Emile Jacqmain, the Boulevard Adolphe Max, the Boulevard Anspach and the Boulevard Maurice Lemonnier. The vaulting of the Zenne meant a radical intervention within the urban fabric, profoundly changing the historical center in the name of its progress, hygiene and beautification. In the 1970s the Zenne was to move again. This time because of the construction of the pre-metro that followed the north-south axis and was built in the tubes of the Zenne. Today the Zenne makes an underground curve around the city center following the inner city ring road.

Brussels is not the only city where the Zenne disappeared. Also in Soignies
and Vilvoorde the Zenne disappears underground.

Because the river has been diverted, polluted and forgotten, its surroundings became a site for all kinds of informal use. The decades-long absence of a comprehensive and inter-regional planning policy, fueled by the ostrich politics of the three Belgian regions, has made the river into a ‘non-place’ or ‘fringe’. The Senne manifests itself as an area of transgression, meandering through city and countryside. The Transgression/Transition project explores the river with these considerations in mind and tries to see how its surroundings today offer room for that what falls outside the norm.

However, there appears to be a growing consciousness among planners and
politicians for the revaluation of the Senne valley. Today the transgressive
space of the Senne is in transition: in view of the potential economic and
commercial interests parts of the river and its surroundings are being
(re)developed. In such a situation of valorization all the facets of the space
come to the fore: the use and its users, the stakes and those who hold it.

By taking the river as its directory the Transgression/Transition project wants to explore the surroundings along the Senne in order to visualize and outline the traces of both formal and informal spatial use.

During my walk the regional area destination maps formed the basis on which I conducted my research: within the context of those areas I searched for both informal and formal use of space. To be consequent I continued looking for a set of parameters that represented the informal and formal. Every time I encountered one of those parameters, I took a photograph and made notes on my maps.

Informal parameters:
Informal paths, graffiti, dumped trash, sleeping places, fire places, cut open
fences, ruins, wastelands and hand written signs.

Formal parameters:
Prohibition signs, information signs, fences, camera’s, place and street names, water treatment plants, new constructed parks, and infrastructures.
