The purpose of this study is to examine the activities of Donuimun Museum Village to preserve the history and memories of the city from the perspective of Ecomuseology. As a historical and cultural city, Seoul is still developing into a cosmopolitan city. Preoccupied with construction industry development, Seoul has recently attempted to preserve the history of the capital city through urban regeneration, which is linked with museum activities. One of the annexes of the Seoul Museum of History, Donuimun Museum Village built around the Donuimun History Museum is an example of turning the entire village into a museum, showing the passage of time through the area called Saemunan neighborhood. Based on ecomuseology, this paper analyzes the contents of this village museum to discuss the roles of the museum in contributing to the local community. Public museums established and run by local governments should be operated with a focus on the relationship with the local community. In this situation, the methodology of the ecomuseum can provide an important clue. The new initiative of Donuimun Museum Village can be highly appreciated, but there are many challenges to be solved. Various reflections should be sought in order for the museum to become an open space for local residents, rather than an isolated castle.
