The Campo de Calatrava volcanic field is a volcanic field in Spain. The field has an area of more than 5000km2 and more than 300 individual structures next to Ciudad Real and contains pyroclastic cones, lava domes and maars. The field erupted basaltic to foiditic lavas from the Pliocene to the Holocene in Columba volcano with phreatomagmatic activity, and fumaroles were observed in the 16-18 centuries in the Sierra de Valenzuela territory. Earlier activity has been subdivided in several phases.
