Twenty-one of the original 31 towers remained when the form was written.","why_significant":"The nomination calls the towers the only remaining examples of a tower lighting system once popular in U.S. cities in the late 19th century. Austin acquired them in a trade for a city-owned railroad, and residents have repeatedly defended them against removal. The towers are valued as reminders of the city's past and for their engineering interest.","narrative":"Austin's Moonlight Towers are a set of tall iron lighting structures built in 1894-1895 to light the city at night. The Fort Wayne Electric Company erected 31 of them, each 165 feet high including its pedestal, with a triangular cast and wrought iron frame steadied by tension cables. Each originally held a cluster of six carbon arc lamps, later replaced by incandescent and then mercury vapor lamps. The city obtained them in exchange for a narrow-gauge railroad and cash, and they were first lit on May 6, 1895. By the 1970s, 21 towers stood at sites across the city, with the rest lost to traffic accidents, storms, and rust. The towers are believed to be the only surviving examples of a lighting system once common in American cities. Residents opposed their removal, and the city moved one tower for a street widening and built a replica in Zilker Park in 1967. They became a state landmark in 1970.","period_of_significance":"1894-May 6, 1895 (built)","architect_builder":"Fort Wayne Electric Company, Fort Wayne, Indiana","architectural_style":null,"criteria":[],"status_note":"Twenty-one of 31 original towers remain.
