All city residents want to live comfortably in their space, therefore, it is very important to take care of the landscape elements. We pay attention not only to places for waste segregation, public benches or playgrounds, but also to quite specific components of urban life. Of course, this applies to urban decorations that should please the eye of passers-by and build a coherent image of the city. After all, it is a natural human need to surround oneself with aesthetic objects. As the awareness of this subject is increasing among city authorities and local communities, one can notice more and more interestingly developed urban spaces. We admire various art installations, exhibitions of local artists and commemorative plaques. At such moments, however, one question arises: could urban decorations also perform practical functions?
