The roof of the 2012 London Aquatics Center is in place

This structure will be a very impressive Aquatics Center and a wonderful legacy of the 2012 games. I hope some day that I can swim there.

From the Guardian:

Swimming is the number one participation sport among women, and Adlington is one of the stars who organisers, who brought the Olympics to London partly on the promise of leaving a legacy of sports participation, hope will help inspire more physical activity among women.

The unveiling of the framework for the sweeping 160-metre roof on the £244m aquatics centre, designed by Zaha Hadid, is seen as a key moment in the Olympic Delivery Authority's "big build". During the games the centre will house two 50-metre pools, a 25-metre diving pool and 17,500 spectators.
