The Cárcavas de Marchal Natural Monument is a spectacularly eroded clay massif covering 5.2ha. For many years people have been carving out caves in the Cárcavas de Marchal for habitation. Located some 55km east of Granada city, Marchal is south of Purullena, off the A92 motorway.

This village was founded in the Middle Ages from a farmstead created by the Moorish era. There are also vestiges of millenary civilisations in Marchal, as can be seen in its archaeological sites.
