Játiva (häˈtēvä) [key], town (1990 pop. 25,577), Valencia prov., E Spain, in Valencia. The town is a processing and distribution center for farm products. Its famous linen industry dates back to Roman times. Játiva was liberated from the Moors by James I of Aragón in the 13th cent. There are many fine public and private buildings, notably the well-preserved Spanish-Moorish castle, a former Mozarabic church, and the Gothic collegiate church (15th cent.). Játiva was long the residence of the Borgia, or Borja, family. Popes Calixtus III and Alexander VI were born there, as was the painter Jusepe Ribera.
