This white village is famous for its orange groves and its emblematic half-moon-shaped, steel truss-girder bridge which spans the river Guadario as it flows down to the Mediterranean. San Martín del Tesorillo is 22km south-east of Jimena de la Frontera, in the Campo de Gibraltar, right on the border between Cadiz and Malaga provinces. It became a 'entidad local' (sub-district) of Jimena in 1999.
