ABSTRACT
In the last thirty years, many interventions have been carried out in the Iberian Peninsula on our monumental rammed earth architectonic heritage. Thirty years ago, when the first actions were carried out (Niebla City walls, 1979), there was a scant corpus of knowledge about building techniques, but still less was known about the sort of interventions to carry out. In time, the professionals and technicians who took part in this type of architecture experimented with criteria and techniques related with their knowledge and experience to achieve the best possible results.
