They have in the area that in the 15th century, when Isabel La Católica was traveling to the conquest of Granada from Córdoba, it reached this point where Guadalquivir was so grown that it did not allow its passage. In one night, according to the book, his gentlemen raised this robust bridge that allowed him to reach Baza and Guadix.

The place is beautiful by itself: the bridge is surrounded by fig trees and wild rosals. And in the paths around it you can observe boj, strawberries and hazelnuts.

On the right side is joined the Maillar stream - with another beautiful stone bridge - which makes in rainy years the place an authentic vergel and a very busy bathing area.

We suggest:

• Make walking some (or all) part of the road that leads to the birth of the Guadalquivir. They are about 11 km across the Navahondona- Guadahornillos Reserve Area, the most protected area of the Natural Park.

In Cazorla take the Sierra road (A-319) until the crossing known as the Empalme del Valle, 17 km. Turn right on the JF-7092 road and after passing the bridge over the Guadalquivir River (4 km from the Empalme) follow the right track (JF-7091) that after two kilometres reaches the Bridge.

The Mengibar Dam was an important civil work in its time, as it was among the first hydraulic power plants to be built in Spain with mobile doors. Until then, the dams were fixed and, if they exceeded their capacity, overflowed. However, in the case of Mengibar, in anticipation of possible floods, Mengemor engineers designed to install mobile doors that allow the water to be depacked in a controlled way to the river. Built from load walls, with natural stone masonry, lacquered and assembled by concrete mortar. The holes form a half-point arc with material of similar characteristics. Covered with flat ceramic tile, mounted on metal fences. It is in good conservation and is currently used to generate electrical power and inject it into the network.

Although it is possible to reach the Poyos de la Mesa from different places, we propose to do it from the track it leads to the Nava del Espino. From this point comes a path marked as PR-A 315 that in an hour and a half leads you to the top of this mountain.

Once at the summit you will discover a wavy landscape of limestone eroded by the passage of time and covered with green meadows and larive pines. It is a formidable place to see the great herbivores of the Park that pasture to pleasure the juicy grass of these heights. It was also one of Felix Rodríguez de la Fuente's favorite places to shoot some of his famous wild scenes.

Now you have to enjoy the landscape around you and identify the many peaks you can see: The Banderillas, the Cabañas, the Empanadas rope, or the Pico Giillo are some of the most emblematic mountains of the Natural Park.

In these saws, it is known as "poyos" to the high plateaus surrounded by cliffs cut to peak, like huge teeth. The Poyos de la Mesa is one of the most spectacular. From its edges you can see a good panorama of the head of the Guadalquivir and if you look at the slices or poyos that name this mountain.

We suggest:

• Once located in the Poyos you should not leave the opportunity to approach the area of the Marchante Prairie, by the bank of the Gualay Tornillo stream.

In Cazorla take the Sierra road (A-319) until the crossing known as the Empalme del Valle. Turn right on the JF-7092 road and after passing the bridge over the Guadalquivir River (4 km from the Empalme) follow the left track (JF-7091). Continue this track to the Nava del Espino in km 21 of the road signs, where you will find a milestone that points to the rise to the Poyos.

Its construction ended in 1789 and retains the colonial typology of these buildings intended to store the grain and seed, control and regulate its production, as well as its redistribution.

Rectangular plant with factory of thick walls covered with sandstone silery and resistant interior arches. It originally consisted of a single plant, but then a second was built.

The Pósito de laboradores has been used as a warehouse, civil guard headquarters, dusty during the War of Independence and children's school.

The plant is in the form of "U" and has only one height. The main ship is divided lengthwise by a half-point archer on square pillars, an archer that runs parallel to the main plane, and on it is another series of half-point arches. It has recently been rehabilitated as a library and cultural center.

In 1572, the cantero Pedro Venetian and the mason Luís de Vilches committed themselves to building the posio, in accordance with the conditions and traces dictated by Andrés de Vandelvira. The building, of a rectangular floor, defines the confluence of the streets Corredera and San Antón with the square of the Constitution. It rises in the planned enranche in the 16th century, outside the medieval compound, essentially formed by the castle and the Renaissance church raised at the foot of it, in which, although perhaps not directly, Andrés de Vandelvira was able to intervene.

The ground floor, with a stone factory seen, is most likely the best preserved part, as the high ones (originally compartmentalized in trickery and built in brick and masonry) were later adapted for other local administrative functions. The singularity of this building is in the division drawn by Vandelvira on the ground floor, made up of five small rectangular ships covered with parallel half-barrel vaults, popularly called the "positillos," built in silery, which communicate directly with the outside based on half-point voids, being the largest central than the other ones.

Typically Vandelvira acuña a model, developed in such a way in the Pósito de Baeza, in which the knowledge of the stereotomy or cutting of the stone requires a great perfection due to the need for the isolation of wetlands to preserve the genre stored in the best conditions. Several heraldic shields are preserved in the building and, as a reminder of the recovery of the advance of Cazorla (in which the villa of La Iruela was included) by the Archbishopric of Toledo, in the early 17th century was placed by the command of Archbishop Don Bernardo de Rojas and Sandoval in the capitular room an allusive inscription to perpetuate this important event. A lot of effort and money cost Toledo's mitre to be made again with her old territory, which was taken from her in 1545 by Don Francisco de los Cobos, Secretary of the Emperor Charles V.

The route of the Borosa River, between the Piscifactory and the Cerrada de Elias, allows to observe a varied set of folds. The structure of the Sierra del Pozo, in which the Borosa River is located, is characterized by the presence of folds and NNE-SSW direction failures. The general geological structure of this Sierra is controlled by two large synchlinals: the birth of the Guadalquivir River and the Cabañas River.

In the four initial kilometers of the itinerary that part of the Piscifactory, folds associated with those of a regional character are observed, the size of which ranges from 1 meter to several tens of meters. These are developed in Cretaceous materials of Urgonian facies and their orientation determines the course of neighboring streams, with the concordant relief of the Arroyo de las Trout valley controlled by a spectacular sinchinal. As an example of anti-linear, the best fold is found in the Los Caracolillo Bridge.

Located between La Mella and Jabalcuz, Mount Almodóvar is famous for its crest, visible almost from any point in the city of Jaén. With 992 meters in height, this hill does not stand out for its altitude, but it does stand out for hosting very close places for the Jiennans, such as the Fuente de la Peña or the Plazoleta de las Armas. The Plazoleta de las Armas is a small plain surrounded by almonds, majolets and pines that offers beautiful views of the city. Place of play, walk and "bulls" of several generations of jiennenses, this square - which is accessed from the district of the Gloriet - remains a special place worth visiting.
