LONDON—London's mayor Boris Johnson is hoping to create a "legacy" of the 2012 Olympic Games by transforming the 500-acre Olympic Park into a national attraction after the games, with one option being a Guggenheim Museum, reports Bloomberg. Other ideas discussed by London officials are a university campus or a "Hyde Park of the East End," all with the intent of attracting visitors to London. With a budget of £9.3 billion ($18.18 billion), the 2012 games are Europe's largest public construction project.

"After the cheering has ended in the stadium and the crowds have gone home, you have to make sure that the legacy is not a bunch of weed-covered ruins," Johnson said.

The Olympic Delivery Authority has already said it would convert half of the venue into a 100-hectare (247-acre) public park set to open in 2014. It would be the largest public park developed in the city for 150 years and would be similar in size to Hyde Park.
