Illyrian Iapydes (or Japodes) tribes had an affinity for decoration with heavy, oversized necklaces made with yellow, blue or white glass paste and they are known for their large ornamented bronze fibulas, spiral bracelets, diadems, and helmets made out of bronze. Small sculptures of jade made from the archaic Ionian plastic are also found in Japodian tribal areas. Numerous monumental sculptures are preserved, as well as walls of a citadel called "Nezakcij" near present-day Pula, one of the numerous Istrian cities from Iron Age.
