For years, French photographer Ludwig Favre has been doing a series on the swimming pools of Paris. The first one he photographed (and the first photo below) was the Piscine Pontoise. Designed in 1933 by architect Lucien Pollet, Pontoise was one of four pools that he completed for the Piscines de France at that time. Another one of his designs was the Piscine Molitor (second picture below), which is the most famous of the bunch for a few reasons. It was the place to be seen in Paris when it first opened. It was where the world's first bikini was apparently unveiled. And it was also abandoned and almost demolished, during which time it got filled with street art. If you aren't familiar with the work of Ludwig, I would encourage you to check out his portfolio. He does an incredible job showcasing these pools, as well as many other aspects of our cityscapes.
