The Najerilla flows from the mountains of the Sierra de la Demanda to
the River Ebro in the western part of the province of La Rioja in
northern Spain. Here fieldwork and excavations from 2000-2003 examined
the varied landscapes of the valley and focused on the excavation of two
Iron Age hilltop settlements, Castillo Antiguo and Cerro Molino. The
work on Cerro Molino was the most extensive and exposed close-spaced
buildings of mud-brick and timber belonging to the Celtiberian period
(fourth-second centuries BC) but both hilltops were occupied in earlier
periods from the seventh to the fifth centuries. Full reports are given
of the structures, material culture and economy of the settlements
together with accounts of extensive field-walking undertaken in the
vicinity. The report concludes with a wide-ranging overview of the
archaeology and history of this hitherto little known area.
