The Winslow Arts Trust (WAT) is a public benefit nonprofit organization that enriches the historic communities Winslow, Arizona, and Las Vegas, New Mexico. The Trust’s goals are to preserve the Fred Harvey structures found along Route 66 and the Santa Fe Railway and to support the artists who are inspired by these places and their histories.
The Winslow Arts Trust was created in 2010 by La Posada Hotel owners Allan Affeldt and Tina Mion, who then transformed the historic railroad depot adjacent to the hotel into the Affeldt Mion Museum (an independently operated venue).
The 7,000-square-foot Affeldt Mion Museum encompasses both the restored La Posada depot, designed by Mary Colter in 1930, and the Licher Gallery, a contemporary exhibit space. The Museum displays works from the WAT collection and special exhibits that explore the cultural and artistic influences of Route 66 and the Santa Fe Railway.
In 2018 the Winslow Arts Trust purchased the Plaza Hotel (1882) and Castaneda Hotel (1898) in Las Vegas, New Mexico.
