Ilfeld Auditorium on the campus of New Mexico Highlands University was Las Vegas' last great expression in monumental sandstone. Las Vegas business tycoon Charles Ilfeld contributed funds to build this lovely auditorium in memory of his wife, Adele. This dignified building has beem declared to be New Mexico's finest example of Romanesque Revival style, typified by the heavy Roman arches and simple Tuscan columns. In form and organizations, the purplish-sandstone facade is derived from Early Christian basilica prototypes.
