Excavations at the Celtiberian strongholds "Kontebakom-Bel" Botorrita, "Sekaisa" Segeda, Tiermes complement the grave goods found in Celtiberian cemeteries, where aristocratic tombs of the 6th to 5th centuries BC give way to warrior tombs with a tendency from the 3rd century BC for weapons to disappear from grave goods, either indicating an increased urgency for their distribution among living fighters or, as Almagro-Gorbea and Lorrio think, the increased urbanization of Celtiberian society. Many late Celtiberian "oppida" are still occupied by modern towns, inhibiting archaeology.
