Since last century the world of entertainment have gained an important weight in modern life and from the creation of large events that recall ancient traditions to create interest like the Olympic Games; and this events needed infrastructure and venues where to be held. This venues created in the last decades have developed a negative reaction in cities, where this venues were supposed to be a legacy and instead are great abandon buildings to be used only for I or 2 months. The proposal of this project was to create an Olympic Stadium that could create a positive legacy to Hamburg, that continue a process of requalification in the centre of the city were the harbour was located. The first study was made in mega-events to justify the election of Olympics and its legacies; then a process of selection of the city, using as based the reports of the IOC (International Olympic Committee) and the cities that had already made a step forward to held the Olympics in the year 2024. In the third chapter we analyse the infrastructure and history of the city of Hamburg and the harbour. Then the study of stadiums, the process of design and the requirements of International Associations to create a stadium capable of held the most competition possible. The final chapter is the project and drawings of the decisions took to realized it.
