Olympic Park, London, E20 2AQ
Another of the Olympic Park's iconic buildings, the Aquatics Centre will be the first building many spectactors see - it's on the approach from Stratford Regional station, with visitors crossing a vast bridge that conceals the training pool, a river and a railway line.

The Aquatics Centre was designed by Iraqi-born starchitect Zaha Hadid in typically uncompromising style. Its talking point is the huge, wave-shaped roof - steel and glass on the outside, treated timber within - that is flanked by 42m-high temporary stands on either side. These will accommodate 15,000 people, with a further 2,500 seated on permanent concrete terracing. Inside, there are a 50m competition pool, 25m competition diving pool and a 50m warm-up pool. The first of 180,000 pool tiles was laid by world record-holding swimmer Mark Foster on 23 September 2010; the venue as a whole will use more than 800,000 ceramic tiles.
Location: In the south-east of the Park, between the Olympic Stadium and Stratford City
