The Montezuma Castle is a 90,000 square foot, 400 room Queen Anne-style hotel building erected just northwest of the city of Las Vegas, New Mexico in 1886 (the site was at the time called Las Vegas Hot Springs, but is now known as Montezuma). The current castle is actually the third on the site, the first two (dating to 1881 and 1885) were the first buildings in New Mexico to have electric lighting, and they both burned down.
In 1981, the castle was purchased by industrialist and philanthropist Armand Hammer for use as a United World College. In 1997, it was placed on the list of America's Most Endangered Historic Places by the National Trust for Historic Preservation.
