Swimming Pool Where You Can Watch Under or On Top -- The spectators can watch the swimmers from either under or above the water-line. A swimming pool with under-water windows has been opened at Gloggnitz in Australia. It was opened recently on the occasion of the Australian Youth Swimming and Diving championships and is regarded as the most modern open-air swimming pool in Australia. This is a real fish eye view of swimming. Unlike fish, however, you can keep dry and warm while watching the swimmers enjoy themselves under water. August 5, 1954. (Photo by Paul Popper Ltd.).
