Belgrade lives, we are already very much accustomed to the sights, sounds and smells, now we desire to go further. We want to move the boundary of getting to know the city, fascinated by the number of the capital parts that are much less alive. We are not entirely sure from where the need to explore buildings without program comes from. We will potentially get to that conclusion somewhere in the process. For now we think that it depends on the place. Some facilities are fascinating by the ways in which they defy time and change, because of their distant history, which today few remember, and to which they no longer remind us. Some of them have too diverse history that they could be a monument only for one period, and in some ways they seem like they have given up and they currently simply exist. The next group of buildings is interesting in quite a different time, not because of their own history, but because of their potential future. And finally, there is the last one, it seems to be the most numerous group of buildings, for whose research we can not state a specific reason or goal. We are sure that we are not alone in the need to walk where it looks like no one else has, for a long time. Each of these buildings has its own energy, but what they have in common is the feeling that they awake in us as we pass through them, the mild sense of fear, the unexpected adrenaline flashes and the inspiration they manage, without a failure, to wake up in us. This is what makes these buildings alive. Some other sounds and scents fill these places, the sounds and smells of the air that is constantly moving through the holes and cavities, which strikes the broken window glass and moves the old carpentry. We need to get to know this other side, we need to remember Belgrade.
