The cities who hold the summer Olympics every 4 years benefit from the event in a multitude of ways. Outsiders are exposed to a country's culture and values, which can increase understanding, and the influx of visitors brings billions of dollars into these regions. The recent standard set by Beijing, China has put a lot of pressure on the Olympics' next stop, London, England. England's political and Olympic officials are up to the challenge, however, and have begun "Europe's largest regeneration project" in the previously neglected area of the Lower Lea Valley.
The project calls for the construction of a park almost 1 square mile, including gardens, wildlife areas, and amphitheaters for outdoor concerts and festivals. This project will mark the largest constructed park in London since the 19th century. Architects have included paths for bicyclists and pedestrians throughout the park that connect the Valley with the Thames River nearby.
Sustainability is the main concern, as many Olympic projects can become grandiose and unrealistic for long term use. The goal will be to create excitement and hype around the project without alienating residents by creating a 'one and done' feature within this historic city. Other projects being complete for the 2012 Games include the Athletes Village, the city's largest natatorium, and a new Olympic Stadium, all of which maintain this idea of longevity. The juxtaposition of these new developments amongst the background of a rich European architectural history will be exciting to see, and with each Olympic Games being more anticipated than the last, the entire event is sure to be a success worldwide.
