The first human settlements in the mountain range of Hornachos are dated from prehistoric times as shown by the cave paintings in the quartzite rocks.

During the Visigoths' time the tradition sets Hornachos as the refuge of Saint Hermenegild when escaping from his father, King Leovigild.

In 1234 Hornachos was occupied by the Order of Santiago, as a land grant by Ferdinand III of Castile,[2] However, this was not originally a cause of concern for the majority Muslim -then Morisco after 1502- population.

Nowadays the village keeps the heritage from the past in its steep streets following the Moorish building schemes as it is shown in places as Ribera, San Francisco, Chamorro, Peña, Enfermería o Plata, Tellada, Larga, Gata, Nogueras, etc.

The most characteristic and outstanding site of Hornachos is its castle built on the top of the hill by the berbers in the 9th century and whose remains observe the daily life of the hornachegos.

Other landmarks include the Franciscan Convent of San Ildefonso, founded in 1526 by Charles I of Spain, and which keeps a rich set of altarpieces, paintings and sculptures.

An important site is the Church of the Remedios, built in XVI and remodeled in 1892, surrounded by a square covered by palm trees and where the festivities of September are celebrated.

Within this area a curious plant, the Erodium mouretii, grows being an endemic species only present in some spots of Extremadura, Andalusia and Northern Morocco.

On 15 May, San Isidro, Hornachos begins a traditional feast where all the inhabitants share a nice country day to eat and drink with their neighbours.

However the most important festivity begins 8 September, Nuestra Señora de los Remedios, patroness of Hornachos, where the whole village organizes parties, shows and encierros ("enclosing") of the bulls, when they are driven through the streets behind crowds of skillfully dodging men and boys.
