For a long time this building was used as the town’s communal granary and later became the bakery. It is therefore particularly well suited to house a permanent exhibition explaining how it operated as a flourmill over the centuries. It also explains the history of the town.
In the Museo Local y Centro de Interpretación de la Prehistoria del Poniente Granadadino there is an Archaeology Room, in which many archaeological fragments found around Villanueva are on display. Of particular interest are the following:
- Palaeolithic flint artefacts, found on the banks of the local river. The existence of a river guarantees water and attracts animals. For that reason it was a good spot for hunting and a convenient place for people to settle.
- Neolithic axes: Some of the first agricultural tools that came into use.
- A bell jar.
- An impressive collection of coins dating from the Roman occupation up to the Spanish era.
- Arabic artefacts such as a clay lamp.
