The implementation of the Schengen Agreement in 1995 effectively transformed the European Union into one continuous zone of free movement. The borders of the signatory countries—which had been fought over and jealously guarded for many centuries—suddenly became porous, vague even.

The first Arab revolutions, starting in 2011, created a surge of immigrants which led to a careful review of the Schengen agreement. In a short span of time, sudden, drastic changes to Europe's sense of territoriality made clear to me how the notions of boundaries had started to become fuzzy.

To help me think through these questions, I decided to approach the limits of my homeland, France. I decided to test my mental map of the country with the actual, geographical edges of its territory.

By positioning myself on the borders of France—its extreme points in the ocean, its international tri-points with Italy, Germany, Spain, Belgium, Luxembourg, Switzerland, its furthest reaches, I re-defined its contours for myself and reaffirmed the country's reality. Sometimes, I placed lights on the border lines to make things clearer. Other times, I found only haziness. In other words, by going to the ends of my country's territory, I pushed to the very limits of what France still means today.
