This thesis is focused on the matter of bells and bell-towers within the landscape. Their importance and use in the presence, and in the past. It also describes the regional spread of bell-towers in Slovakia. The regional variability within Slovakia has been described accordingly to chosen examples analysis. There is a wide range of various bell-tower types in Slovakia. Differences are noticable through the whole country from the west to the east, and from the north to the south as well. Differences lie in the architectural interpretation, and in the placement of bell-towers in the landscape. This work showed that it's difficult to identify straight borders of specific bell-tower regions.
