This study investigates the case of tourism in Tamsui, and the complexity in the structure of tourism. The author also investigates into the history of Tamsui of the recent decades as the study background. Colonization and development of foreign culture have brought Tamsui the indispensable space experience, and have left Tamsui the potential for tourism. It still takes a duration of time for the development in Tamsui and the mutual understanding to be established through day-to-day activities.
