London 2012: Olympic Park time lapse photography

Progress on the London 2012 Olympic Park became clearly visible this week as new images revealed the columns of the Olympic Stadium emerging from the ground. Over 100 columns, each 5 m tall, have already been constructed and act as the support for the podium of the Stadium’s west and south stands. This also forms the lower ground floor of the West Stand, which houses the athletes' changing rooms, a 60 m long call track and other back of house facilities such as doping control and treatment rooms.
