In western Paris, the swimming pool where national hero Leon Marchand won four gold medals at this summer's Olympics in the French capital is being stripped down and prepared for a move. The pool was part of one the many temporary sports facilities used during the Games, built inside the Paris Defense Arena, a stadium to the west of the city which was deafening during each of Marchand's medal-winning exploits. Around 25 kilometres (miles) of scaffolding are being pulled down by the pool, while the 50-metre water basin itself -- made of hundreds of aluminium panels bolted together -- will soon be dismantled and sent by truck to a new home in a northern suburb.
