One of the more impressive design feats of the Olympics, the Aquatics Center will host diving, swimming and artistic swimming events for the 202 Games. The building has been admired for its unusual construction method in which the large roof was constructed on the ground and then raised later. It should be finished in Spring 2019 and theres a pretty impressive time-lapse of the construction so far. After the Olympics the center will become a community leisure center with goals of over a million visitors a year.
