Heritage towns in Huelva
3 towns in this province.
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.
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.
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.
