In recent years, lots of papers are fast reacting to overtourism, making it open for discussion and finding the solutions. Specifically, in the European context, cultural tourism is the fastest-growing sector in the tourism industry, which is the leading cause of overtourism. Furthermore, globalization makes cultural tourism gradually become mass tourism, result in even worst situations. There is a global trend indicates that the urgent need for change from cultural tourism to creative tourism, to achieve a better-integrated tourism system within a city. The project aims to choose one of the historical tourist cities in Europe as the experimental site for researching and solving overtourism problems by the development of creative tourism. Hungary’s capital city-Budapest is the only international city within the country, almost 75% of the country’s tourism revenue is generated here by the development of cultural tourism which can be reflected on its highly centralize cultural facilities and accommodation within the inner city, resulting in the concentration of the tourist bubbles. The project explores how to implement transitional zone(brownfield) as the place to develop creative tourism as the strategy to affect the tourist movement patterns, in order to reduce the pressure of tourist bubbles concentrating in the inner city. Eventually, the development of creative tourism in the transitional zone can relieve the pressure on the historic inner city of Budapest while regenerating the brownfield within the city, increasing both the quality of life in the historic inner city and the neighborhood in the transitional zone, leading to socio-economic growth for the city.
