The purpose of this study is to analyze the historical development of Seoul Station's space and contemplate the current state. The history of Seoul Station began in 1900 and has since interacted continuously with the city. Through the Japanese colonial period, the Korean War, and periods of rapid growth, it has undergone dynamic changes. As a result, it has grown into one of Korea's most important stations and developed into a hub for high-speed rail. In this process of change, Seoul Station has influenced its surrounding environment and undergone changes in its functions. This study aims to analyze the history of these changes and reflect on the issues that have arisen during this development.
