All tangible and intangible elements of cultural heritage that the past has conceded to local communities create unique landscapes shaped by tightly connected anthropogenic and natural factors. This heritage is a keystone of local identity which plays a significant role in politics, economic development, society and world view. In some regions, such as in the Vistula delta in Poland, the cultural heritage has been created by consecutive groups of settlers who represented different values, beliefs and ways of life. On the one hand, such a rich heritage may be perceived as a valuable asset and become a landmark or tourism product of a region. On the other hand, it may be perceived as alien and unwanted by contemporary residents, especially when they are not descendants of the former communities. The main objective of the study presented herein is to analyse how the residents of the Vistula delta region, called Żuławy Wiślane, perceive and use cultural heritage of the Mennonites, representing the most extraordinary group of settlers who used to live in the region. The analysis covers original data gathered during survey research in the period of 2017–2018 under the project Miniatura I “Perception and usage of cultural heritage of the Vistula delta Mennonites” financed by the National Science Centre in Poland.
