The castle at Hornos del Segura is in use today as a museum and cosmolarium
Castillo de Hornos
The castle at Hornos overlooks the village of Hornos that is in the Sierra de Segura in Jaén province. The castle is in a strategic position at the highest point of a limestone buttress that rises from a valley that was both fertile and had one of the few tracks between the mountains of the Sierra de Cazorla and the Sierra de Segura.
Hornos village beneath the castle
Castillo de Hornos was founded by the Muslims in the 9th century. During the late 12th and early 13th century, in response to the advance of Christian forces from Castile and Leon, they built a keep and three small towers with a connecting wall that surrounds a parade ground and dug a well, all that remains from that period. The keep is interesting in that it had rounded corners making it less vulnerable to missiles, an unusual feature for the time.

Rodrigo Iñiguez, grand master of the Order of Santiago, conquered Hornos in 1239 and the castle subsequently underwent renovations. Sadly, despite more recent repairs in 1973, the castle is largely derelict.
The parade ground is the location of the new Cosmolarium and the keep contains a museum dedicated to the history of astronomy and space travel. The exhibits in both are very up to date 21st century visual displays.
