Even if youâre not a huge fan of lap swimming, indoor pools are often really special examples of national architectureâmy favorites are from the first half of the twentieth centuryâand itâs surprisingly interesting to observe the pool etiquette of different cultures. Italians, while somewhat impatient and in-your-face on land, are incredibly courteous and respectful of relative speed in the water; theyâre gracious and accommodating if you need to pass them. In Milan I always make a point to go to Piscina Cozzi, which had a huge Maurizio Cattelan mural on the back wall featuring a tacky Ophelia in red lipstick. It was there in October of last year, but I think theyâve since taken it down, which is a shame, but apparently he swims there, too.
