The Mukho Port Railroad district with the receiving and shipping space has been the center of growth in Donghae city since its opening at Mukho Port. However, the value of the economy and space has been reduced due to the restriction of citizen’s access and the decrease of freight trains and fish catches, hence the slumism of Mukho port railroad district is accelerating further. In this situation, this study proposes a regeneration plan of Mukho Port railroad district with the receiving and shipping space to apply it to the Rhizome theory. Therefore, this study suggests the architectural plan that applies the characteristic of the rhizome to the railway dockyard of Mookhohang Railway which has low value of tangible and intangible. The purpose of this study is to investigate the applicability and effectiveness of the restoration plan of the Mukhoang Port Railway Dockyard based on this purpose, I will leave it as a process of the study of practical value.
