Alájar

A mountain village in Huelva's sierra where a twelve-spout fountain gives birth to a river, pouring two million litres a day through centuries-old irrigation channels into the surrounding orchards.

A village in the hills of Huelva whose Arabic name may mean valley of roses or fertile land, and whose history has passed through Moorish hands, Portuguese and Castilian tug-of-war, and eight centuries of quiet mountain life.

On the highest ridge of the Huelva sierra, Almonaster la Real contains one of the oldest functioning mosques in Spain: a 10th-century building on Roman foundations where Friday prayers have continued, on and off, for over a thousand years, and whose minaret now doubles as the belfry of a small Christian hermitage.

Aracena sits above one of Spain's great underground surprises — the Gruta de las Maravillas, a cave of extraordinary stalactites and turquoise pools — and above that stands a ruined Templar castle, while the surrounding sierra is ground zero for the world's finest jamón ibérico de bellota.

A frontier town on the edge of Andalucía and Portugal, Aroche has been occupied since the Stone Age and still stands behind its artillery walls, with a Almohad castle at its centre and a Roman city buried in its fields.

One of Andalucía's oldest continuously settled towns, Zufre rises above the Sierra de Huelva behind medieval walls that once enclosed a city of 6,000, with two surviving fortified towers still standing guard over its historic core.

Niebla is the best-kept walled city in Andalucía: 2.5 kilometres of Roman and Moorish ramparts stand almost perfectly intact around a small town on the Río Tinto, their ochre-red walls stained by the same iron-rich waters that once made this the shipping point for Rio Tinto copper ore.
