Heights of Aguallal Nature · A Mezquita, Viana, Ourense Image of A Mezquita, not of the place itself. A summit of 1,664 metres, the highest point of a municipality whose average altitude tops 800 metres and which for that reason bears the name Terra das Frieiras, where the frosts last for a good part of the year.
