Lately, a two-meter-tall black metal fence was put up around a park next to my house. The purpose of fences is to limit the access to the territory. Why was the park fenced? For me, it remains a mystery. Fences limit the free space in the city, squeeze the surrounding world to the size of a prison cell. Everything in Moscow gets fenced: playgrounds, the areas around apartment or office buildings, hospitals, schools, kindergartens. Even the historic center of Moscow – the Kremlin – is also a fence. And, as is the case with any other fence, the access to it is limited.
