Through the case of urban revitalization by a culture that has brought economic benefits to the community, many local governments plan to build museums as a means of urban regeneration. However, without the consensus or demand of the locals, no matter whether museum is under construction or after, one-sided construction by local government inevitably has many problems. In order to prevent such problems, ‘21st Century Museum of Contemporary Art, Kanazawa’ in Japan operated an pre-opening program for the construction of the museum for ten years before the construction, helping local residents to understand and create an atmosphere for the construction of the museum. Ulsan city tried to solve the problem of typical city center by using the culture-based urban renewal strategy. The ‘Culture Street Planning Project’ and ‘Ulsan City Museum of Art’ are the core of the renewal strategy. As part of this Culture Street Planning Project, ‘International Contemporary Art Project Ulsan’ has been conducted for many years. Art Project Ulsan, a street art festival in the form of a public art festival, played a role as a pre-opening program for Ulsan City Museum of Art. This study examines the cases of urban regeneration projects and cultural activities in Ulsan through the cases of Ulsan City Museum of Art and Art Project Ulsan, and furthermore, it seeks to find out how to create an atmosphere in advance and draw the needs of local residents for the construction of local museums.
