Austin, Texas is the only city in the world known still to have light towers. They are 165 feet (50 m) tall with foundations 15 feet (4.6 m) wide. The towers were manufactured in Indiana by Fort Wayne Electric Company and assembled onsite.[1] In 1894, the City of Austin purchased 31 used towers from Detroit. A single tower cast light from six carbon arc lamps, illuminating a 1,500 feet (460 m) radius circle brightly enough to read a watch.[2]
