The moonlight towers in Austin, Texas, are the only known surviving moonlight towers in the world. They are 165 feet (50 m) tall and have a 15-foot (4.6 m) foundation. A single tower cast light from six carbon arc lamps, illuminating a 1,500-foot-radius (460 m) circle brightly enough to read a watch.

In 1970 the towers were recognized as Texas State Landmarks, followed by the 15 remaining towers being listed in the National Register of Historic Places on July 12, 1976. Only 6 are in their original locations as established by the Board of Public Works and City Council in 1895.


In 1894, the City of Austin purchased 31 used towers from Detroit. They were manufactured in Indiana by Fort Wayne Electric Company and assembled onsite. Some have claimed that Austin put up moonlight towers partially in response to the actions of the Servant Girl Annihilator, also known as the Midnight Assassin, but in fact the towers were not erected until 1894 and 1895, ten years after the murders took place.

When first erected, the towers were connected to electric generators at the Austin Dam, completed in 1893 on the site of present-day Tom Miller Dam. In the 1920s their original carbon-arc lamps, which were exceedingly bright but time-consuming to maintain, were replaced by incandescent lamps, which gave way in turn to mercury vapor lamps in the 1930s. The mercury vapor lamps were controlled by a switch at each tower's base. During World War II, a central switch was installed, allowing citywide blackouts in case of air raids.

In 1993 the city of Austin dismantled the towers and restored every bolt, turnbuckle and guy-wire as part of a $1.3 million project, the completion of which was celebrated in 1995 with a citywide festival. The City of Austin has ordinances in place to protect the towers from demolition. However, since 2004 the towers at 4th and Nueces, at 1st and Trinity, and at West 22nd St. and Nueces have all been removed to clear the way for new construction. It is unclear whether they will be dismantled or erected elsewhere.
