It lies between the Sierra de Huétor Natural Park and the new reservoir of Francisco Abellan.

In any case, it is clear that during the Roman Empire, Diezma was a kind of hospice for travellers who were on the Via Augusta between Acci and Iliberis.

It suffered frequent incursions by the Zirids first, and then knights of Alfonso VI before the final conquest by the Catholic Monarchs.

In 1536, it was purchased from the Crown of Castile by Luis Guiral who acquired the title of Mayorazgo Diezma.

In the 20th century, it was a busy first stopping place on the main road from Granada to Murcia and Almería.
