The Motilla del Azuer is a prehistoric fortification dating from the Bronze Age in the municipality of Daimiel, in the Province of Ciudad Real, Castilla–La Mancha, Spain.

The special characteristic of this site and the massiveness of its fortifications, with masonry walls more than eight metres (26 ft) high, make the Azuer settlement one of the most notable Bronze Age survivals of the Iberian Peninsula.

The central core is a masonry tower with a square floor plan, the east and west walls of which still stand more than ten metres (33 ft) high.

Inside the enclosure between the outer and intermediate walls, there are many circular or oval ovens, with masonry plinths and vaulted clay covers, as well as rectangular silos for grain, which were built throughout the occupation of the site.

[3][1] Since 1974, a team from the University of Granada, directed by Trinidad Nájera Colino and Fernando Molina González,[4] had by 2021 undertaken fourteen seasons of archaeological fieldwork, with the first research phase lasting until 1986.

[1] An interdisciplinary hydrogeological study in 2014 found a relationship between the geological substrate and the distribution of the motillas at Daimiel, considering also that they may be the most ancient system of groundwater collection in Iberia.

The study concluded that the motillas were built in the Bronze Age during the 4.2-kiloyear BP aridification event, due to a period of prolonged and severe drought, and that the building of defended settlements around wells was "a successful solution that continued for about one millennium and formed the main part of the processes of change towards a more complex and hierarchical society".
