When you grow up as a child in a city, you see your environment changing profoundly. Remarkable buildings disappear from one day to another, whole neighborhoods are thrown down, viaducts come and go, new buildings rise ... In particular in Brussels, it is not difficult to find places where at the same location already 3 totally different buildings have existed in a 30-year period. You can therefore not do otherwise than develop an interest in heritage and conservation. Even if you are not particularly interested in architecture. After all, together with the houses, streets and neighborhoods, also the people, their culture and their life disappear. And then only memories and photographs remain.
