Monti's La Casa Vieja was built upon a distinguished tradition of hospitality. We'd love to tell you a little about our establishment and its rich history. Monti's La Casa Vieja is located in Tempe, Arizona, in the city's original pioneer home and the oldest continuously occupied structure in the Phoenix metropolitan area. The original adobe hacienda was built as a home by Charles Trumbull Hayden in 1871. Hayden settled in the area to establish a flourmill and a ferry service for crossing the Salt River, which flowed year-round at that time.
