Perched upon towers

up above the world so high

yielding brighter paths

Photo: One of the 15 remaining Moonlight towers in the world, all of which are in Austin, Texas. They’re 165 feet (50 m) tall and 15 feet (4.6 m) wide. A single tower casts light from six carbon arc lamps, and illuminates a 1,500 feet (460 m) radius circle.
