Overlooking the village, the castle fortress stands on the banks of San Cristóbal, probably the former site of the Roman town of Oba. The current building, of Moslem origin, dates back to the 13C. You enter by the double archway on the large flanking tower which was once the watchtower. The esplanade on the hillside contains the village cemetery, several large water tanks and the wall of the castle overlooked by the large keep.

Manilva's 18C Iglesia de Santa Ana has an unusual doorway consisting of an arch with a whole series of blind arcades - the kind you often see on minarets.

This 18C church was part of a convent of the Tertiaries of St Francis. There is evidence of colonial architecture here, with tree aisles separated by arches standing on pilasters. The remarkable baroque portal is decorated with the sun, moon and stars. Note the coat of arms flanked by two strange heads. A tower with a pyramid-shaped arrow stands above the building.

This museum is in a large house in the centre of the pretty Acacias Park. It contains a number of exhibits from the Roman era including amphora and corks, which show the commercial importance of the bay of Algeciras. Note also the pieces relating to the Siege of Algeciras (1342-1344), during which the troops of Alfonso XI showed much ingenuity
