Built specifically for the London Olympics, the Aquatic Centre construction began in July 2008 and finished in July 2011:

It forms part of the gateway to the Olympic Park — more than two-thirds of spectators will enter the Park at the south-east corner via a bridge that forms part of the venue’s roof.

And, of course, someone built a sweet Lego version of the Aquatic Centre’s diving pool.
