The Parque de los Lavaderos
Back in the olden days, this is where local washer women would come to do their laundry. (I have no idea what the actual time frame must have been, like the 19th century? That feels right, but I'm covering my bases by just calling them the "olden days".) The park is located around a powerful natural spring, and the natural beauty of the area must have alleviated the monotony of the washing.
