Aracena, Mountain municipality in Sierra de Aracena, Spain.
Aracena is a mountain town in the Sierra de Aracena in the Province of Huelva, nestled at around 700 meters elevation. The settlement sits within oak and chestnut forests and contains the Gruta de las Maravillas, a limestone cave system with chambers and pools.
The town grew from prehistoric settlements and passed through Roman and Islamic periods before being conquered by Sancho II in 1231. This conquest turned it into a strategic stronghold for Christian rule in the region.
The Priory Church of Nuestra Señora del Mayor Dolor shows how two different cultures shaped the town through its preserved minaret from earlier times. When you walk through this church, you can see and feel how Christian and Islamic architecture blend together in one building.
To reach the Gruta de las Maravillas, you head through the town center where visitor information is available. Trails wind through the surrounding forests, and small local shops sell regional ham, cheese, and other traditional food products made nearby.
Inside the Gruta de las Maravillas lies an underground lake that glows green on certain days depending on how light hits the water. This color shift happens because of minerals in the water and deposits on the cave walls.
