History of Aracena
The sierra above Huelva has been inhabited since at least the Chalcolithic, and the Aracena area shows evidence of prehistoric mining. The Romans exploited the copper and silver deposits of the wider region. Under Moorish rule the hilltop was fortified; after the Reconquista in the 13th century the Knights Templar controlled the area and built or rebuilt the castle.
The town grew up on the slopes below the castle. From the late medieval period, the raising of black Iberian pigs on the acorns of the surrounding holm oak and cork oak forest became the defining economic activity of the sierra — a tradition that survives as the highest-value segment of the Spanish cured ham industry. Aracena today is the main town and service centre of the Parque Natural Sierra de Aracena y Picos de Aroche.
Heritage & Monuments
The Gruta de las Maravillas (Cave of Wonders), discovered in 1914 and considered the finest cave system in Andalucía, runs for 1,200 metres and includes twelve chambers filled with stalactites, stalagmites, and coloured underground lakes. Timed guided tours run throughout the day. Above the cave, the ruins of the Templar castle and the attached 13th-century church of Santa María de los Reyes occupy the highest point of the town; the views extend over the wooded sierra hills.
The town below has the relaxed atmosphere of a sierra market town with good restaurants serving the local jamón and a weekly market. The Jamón Museum (Museo del Jamón) explains the production of Ibérico pork from acorn to cured ham. Walking trails from the town reach remote villages in the serra.
Practical Travel Info
Aracena is 90 km north of Huelva and 100 km from Seville, reached by the N-433. There are buses from Seville and Huelva. Book the Gruta de las Maravillas in advance (especially at weekends), as tickets sell out.
The old town and castle are free to visit. The sierra is busiest in autumn (ham season) and spring.

Nearby heritage towns
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.
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.
