As you travel north from Minas de Riotinto to Aracena it’s all too easy to miss the village of Campofrio. I’d recommend you make a stop and wander the cobbled streets. Claims to fame: What is probably the oldest bull ring in Spain can be found here. Roman remains and historical evidence dates Campofrio back to the Bronze Age. In the time of the Muslims, Campofrío belonged to Niebla, although the earliest documentary reference to it is later – from 1401, at which time Campofrío was administered from Aracena, from which it split off in 1753. From the second half of the 19th century onwards the locality’s economy was dependent on mining, hence the mining monument in the central square. Campofrio is 80 km. from Huelva and 20 from Aracena.
