The Museu de la Festa documents Ontinyent's Moros i Cristians tradition with displays of historical costumes, weapons, music, and archival photographs. It is a small but well-organised museum that gives useful context before the festival (or year-round for those who can't attend). The costumes on display include some of the finest embroidery examples from the festival's two and a half century history.
Located in the town centre, near the Plaza Mayor. Free admission or very low cost; opening hours are limited on weekdays.
