The amount and size of the Olympic facilities have outgrown the needs of host cities. most Olympic venues cannot be used after the event and maintenance is extremely expen- sive. Therefore cities cannot optimally benefit from the catalysing effect that mega-events, such as the Olympics, can have on host cities. An over-production of sport venues causes bad physical legacy. This research addresses the spatial impact of the Olympics and poses a hypothesis of de- centralisation. Can the spatial impact of the Olympics on a city be improved by decentraliz- ing the event in a regional setting? This document analyses the spatial organisa- tion and impact of the 6 latest Olympics (from Barcelona 1992 until London 2012). The Lon- don Olympics is also thoroughly analysed on the process of hosting the Olympics. All of this is concluded in a strategy formula- tion that poses how the spatial impact could be improved by decentralizing the Olympic organ- isation in a regional setting. This theoretical strategy is subsequently tested on a networked city region. The region chosen is the Øresund region between Denmark and Sweden. The reason for the implementation on this specific region comes from a comparative study between different European networked city region. It is concluded that from those re- gions, the Øresund region has the biggest de- veloping potential and could therefore benefit the most from hosting the Olympic Games. The Øresund region is analysed and a stra- tegic development vision is formulated that integrates the Olympics as kick-starter of the cities' and region's future development.
