Castle of Calatrava la Nueva and Sacred Convent

Highlight • Castle

Settled on remains from the Bronze Age and a Visigothic settlement, this large fortress built in the 13th century is located on top of a hill.

It was built by the Order of Calatrava after the battle of Las Navas de Tolosa, becoming the headquarters of the order and one of the most important defensive fortresses in Castile.

More than a simple fortress, it is a complex that included a church, a convent, a hostel, a town and an external enclosure, all protected by an extensive wall.

It is formed by a Strombolian volcanic cone of pyroclasts, and due to the quarry in it, its internal structure is exposed. Attached to the foot of this volcano is the Almodóvar maar, which is a phreatomagmatic explosion crater that erupted at the edge of the Paleozoic series, cutting a substrate of hard lithology and destroying part of the previous volcano. The maar crater is funnel-type (hard-type substrate) and houses an ephemeral lagoon inside. In its southern and eastern contour the maar has a ring of tuffs, with pyroclastic facies. The phreatomagmatic deposits of the maar ring are located on a Cenozoic red colluvium. The main interest is of a volcanological (petrological) type and as a secondary interest the geomorphological interest stands out.

Laguna Blanca

Highlight • Lake

The Laguna Blanca in Argamasilla de Calatrava is an interesting natural formation. It was created by volcanic explosions that created depressions filled with rainwater1. This lagoon is known for the whitish colour of its waters, a result of the minerals present in the soil, such as bicarbonate and sodium sulphate.

It is an excellent place for bird watching, as many species choose it as a stopover, resting or nesting point. In addition, the area around the lagoon has archaeological remains dating back to the Paleolithic, which adds historical value to the place.

This castle stands on the impressive Alacranejo hill and, despite its original defensive character, it underwent various modifications. Opposite it there is another hill with the ruins of the Salvatierra Castle, in the lands of Calzada de Calatrava. It probably has Arab origins, but it was deeply remodeled with the transfer of the knights of the Order from the Castle of Calatrava La Vieja (Carrión de Calatrava) in 1217, after the battle of Las Navas de Tolosa with the aim of consolidating the defensive line of Sierra Morena. In turn, it is made up of three walled enclosures and is accessed by the original road that was built on the occasion of the visit of Philip II through the Iron Gate, in red volcanic stone. Afterwards, we can find the Gate of the Arches, which allows entry into the parlatorio or courtyard of the convent, the courtyards, the church, the rooms and the refectory. Really, when you walk through it, you can imagine what happened in

It is a volcanic formation made up of a crater and the Cerro de los Molinos. The crater gives rise to the lagoon and the hill is composed of solid lava. It is located near Almodóvar del Campo, in an easterly direction and, according to historians, it gave origin and name to the settlement of the population.
