In the highest part of the hill where the monumental complex of the Alhambra and the Generalife is located, in the Dehesa del Generalife (Granada, Spain) there is an extensive hydraulic complex, from the Nasrid period, which could have been fed by groundwater captured from the Aljibe de la Lluvia. This paper presents the results of a geophysical prospecting survey performed to determine if there hydrogeological conditions to explain the presence of a spring in the Alhambra Formation. The results explain why the water emerges in the vicinity of the cistern and contribute to reinforcing the theory that this spring could condition the establishment of the Alberca Rota hydraulic complex, which was the node that made it possible to supply water to the royal Nasrid countryhouses of Alixares (Qaṣr al-Dishār) and Dār al-’Arūsa (Casa de la Novia), built in the last third of the 14th century.
