As society alters and building ages, many industrial facilities lost their function and abandoned in central city areas, and sometimes creating many problems. However, many European countries successfully transformed those urban decay to vivid cultural hub. The purpose of this study was to analyze a concept and methods of converting idle industrial facilities to successful cultural spaces. A case study of Tate Modern, Baltic Center for Contemporary Art, and Ruhr Museum was conducted using literature review, site visit, and interview methods. Findings indicated that converting historically significant idle industrial facilities to cultural center had not only reused abandoned site but also helped regenerating adjacent urban areas. This article demonstrates the key factors of successful conversion strategies as convenience, participation, placeness, historicity, and accessibly; and thus an effort to actively enhance the strategic factors were demanded in future conversion projects. A continuous studies on exploring extensive cases in various perspectives are required for further generalization in future studies.
