The Olympic Games are the biggest sporting event on the planet, and the redevelopment that is required for their conduction significantly affects the structure of the city. Olympic Parks are the center of the event since most Olympic sports facilities are located there. One of the biggest challenges of such events, in terms of urban planning, is the post-Olympic use of these facilities. This paper deals with the design of Olympic Parks for the Summer Olympics and their post-Olympic use. In this paper, an attempt is made to understand how to ensure a long-term sustainable area that will revitalize the city. Initially, a review of the Olympic Games from their revival in 1896 and their evolution until today. In addition, the reasons why the cities are interested in hosting these events are examined, as well as the benefits they may bring. Furthermore, examples of six cities that hosted the Olympic Games (Munich, Barcelona, Sydney, Athens, London and Rio) are analyzed, which were selected based on their different design approach to the post-Olympic use of the Olympic Parks. The analysis of each city is done by taking into account the use of the area of the Olympic Park before the Games, the park design  for the Games, and their post-Olympic use. Through the comparison of these cities, an attempt is made to identify what could be beneficial or disadvantageous in relation to different aspects of the city.
