Industrial/Technological Cultural Properties are closely related to contemporary life, and have played the dominant role as a bridge between the traditional architectural buildings and contemporary architectural buildings, reflecting the overall economical, social and cultural portraits of that time. Nowadays, due to various sprawling developments and new development-oriented urban policies, only a select few Industrial/Technological Cultural Properties are being protected, the rest facing with demolition and damages. In order to better cope with such situation, Korea has officially introduced the Registered Cultural Properties System since 2001, and began acknowledging the historical values of industrial buildings as modem cultural properties. Under this circumstances, purpose of this study is to analyze main project plans of each facility in Abanoned Nordstern Mine Gelsenkirchen in the state of Nordhein-Westfalen, that have been preserved and recycled as office spaces. and to bring out the main features of the plans, so that they can be utilized to find suggestions for Industrial /Technological Cultural Properties Revitalization.
