Since then, local associations and municipalities have begun to promote this interesting heritage. In 1999, because of the uniqueness, abundance and quality of this industrial mining landscape, heritage experts described the area in the British press as "the best kept secret in Europe" (Europe's best kept secret).

In the entire mining region, there are remains of high interest industrial archaeology, some unique examples in the world. This scattered set of buildings, railway stations, machine houses, chimneys, cabries and roads explain the history of one of the areas of southern Europe in which the Industrial Revolution took place, where English, Belgian, French and Spanish communities lived together. This combination of history and the use of natural resources is an excellent pretext for visiting the landscape of the chimneys, the landscape that welcomes visitors who arrive in Andalusia from the north.

In the magazine Don Lope de Sosa (1924) Don Manuel Muro García published a document of great interest on the conditions developed by Andrés de Vandelvira to make the gallery high, complemented by some explanatory drawings on the margins, which are practically the only drawings, so far, that have come from his hand.

The document is dated May 3, 1561, and - although the architectural forms of the work of the gallery are essentially written in it - Vandelvira, of course, was responsible for much of the building, from which at present the facade has arrived intact. V.M. Ruiz Fuentes provides new data on the constructive process, as it states that the cover and the second body of the facade are already up before 1561, date of the beginning of the upper gallery, finished about 1563.

The palace does not keep the courtyard, which was perhaps also designed by Vandelvira, from which we know that its construction was started by 1564. The large facade of quarry stone, of marked horizonality, is articulated on three floors; on the bottom and centered is the cover, inintered and with two Corinthian columns (with the alternating sticks) on pedestal; on the axis with it is raised in the middle the main balcony stacked and with triangular front, covered with the familiar heraldic held by "savages," to the ends are opened two more balconies with jonic columns with heavy arches and triangular frontons.

Special protagonism acquires the windows in the corner of the noble or intermediate plant, in the way of the palace of the deán Ortega, with central column of white marble, pilasters and triangular front. The gallery on the last floor is made up of a series of arches of half-point on pillars, repeating in the corners the design with a column. This piece is the most plastic part of the whole, due to the wise compagination of hollow and solid, because the rest of the facade is a bit heavy, the isolated elements of it being the ones that give it a loan.

An interesting fact is the use of the balcony, which will slowly be imposed on the window. Finally, it is repeated in this palace the cornisa-internamento, used in the nearby palace of Vázquez de Molina, of a marked Italian accent, in which Andrés de Vandelvira also intervenes and is responsible for much of his factory. Mr Fernando Chueca Goitia said - in the monograph dedicated to the life and work of Andrés de Vandelvira - that the structure of the façade of the house of Vela de los Cobos is radically Spanish and is located in the line of the mature works of Alonso de Cobarrubias, the real architect.

In any case, what was done in this palace by Vandelvira will be taken as a reference point in other Ubetens palaces, such as that of the Marquis de la Rambla (16th century), that of Mancera (from the end of the 16th century), in which the gallery opened in the last body of its tower, or that of the Count of Guadiana, in whose tower, raised in the first two decades of the 17th century, is repeated the model of the sintered balcony with marble column, while reciting in the last body the composition of the gallery. But the gallery of the Vela de los Cobos palace will not only accommodate the large buildings, but will not be used frequently in the popular vernacular architecture of the city of Ubeda throughout the 17th and 18th centuries.

Today only its façade is preserved, highlighting its Renaissance style reflected by the two "tenants" that accompany the shield of the family topped by ducal crown (to the county of Bailén is added the ducado of Arcos) In 1970 it is disassembled piece by piece and installed in its current location.

Without a precise document, however, the intervention of Andrés de Vandelvira in this beautiful building is evident. The traditional historiography has considered it, as it incorporates the stylems used by the Master in other ubetens palaces. Some of the unknowns related to the works have been clarified by V. M. Ruiz Fuentes and A. Almagro García, following the consultation of two notarial documents of the Historical Archive of Ubeda. On November 7, 1575, the singers Juan de Madrid, Juan Hernández and his son Cristóbal Hernández met with Don Francisco de Molina and Valencia to work all the chairs for the façade of his house, but under the condition that they are like those worked in the Vela Cobos palace. On the same date, Juan and Cristóbal Hernández also forced himself to make a "(...) cover and window above (...) and that the stone to be (...) according to the form and form of the cover and window to be questa date in the main houses of Francisco Bela de los Cobos, deceased (...) and to be of the size and height and length that the cover and window has the stones to make the savages." The documentation is very clear in relation to the date of the start of the works, months after the death of Andrés de Vandelvira, set in April of the same year of 1575.

It also seems to be inferred that, by the express desire of the comitant, the cover would be drawn following the model already coined in the city by Vandelvira in the Vela Cobos palace, although with obvious changes. The facade, composed of two separate bodies, is decorated with diamond tips. The cover, located on the left end, is made up of a lintel flanked by Corinthian columns (with alternating acanalions and batons) and high backpilasters on the bases, completing on the upper floor with a vanity entangled with Ionic pilasters with alternating batons, entment and triangular front with mirror on the eardrum and pinaculars on the vertices, repeated in the rest of the voids, two of them open to a beautiful balcony. This beautiful façade is topped with a cornice decorated with mends (to play with those placed on the cover) and mascara. After a large zaguan the courtyard is given way, previously built.

From the 16th century there are two galleries with double panda, made in different years and with designs somewhat outside the local architecture of this period; from the 19th century are the two remaining. The ensemble is monumental and has a pleasant charm, certainly propitiated by a generous vegetation and a central source.

It is the seat of theArjonilla Museum Collections, opened in 2018. It has a room dedicated to the archeology of the municipality, another is the Hall of Reproductions of historical ceramic of the pottery Manuel Bejarano, in short will have other rooms dedicated to the traditions of Arjonilla to illustrious characters....

The cover has an intellized entrance, flanked by columns on pedestals and on which there is a balcony with a heraldic shield. The tower, a primary element of the building, follows a distribution of four bodies, in which the upper open gallery, decided in a similar way from other Renaissance of the city, stands out. It highlights the decoration of the windows, in which pagan and Christian themes are mixed. The courtyard is the central axis of the building. It has a simple quadrangular, two-storey courtyard and wooden bovedillas in the roof of the galleries.

At this time it was sold and dismantled and dedicated to school, offices, headquarters of the Civil Guard among other uses. Until 1871 it was the seat of the City Council. In the 20th century, part of the building became a theatre, in 1945 it became municipal property and was transferred to the Ministry of Agriculture, for the National Trigo Service in 1958. It was in 1972 that it was again owned by the municipality.

Its Neoclassical style construction of monumental order and crowned by the shield of Charles III, makes this building the emblem of La Carolina as Capital of Las Nuevos Poblos.

They highlight the sun clock located on one of its corners, set to give the time to the steps that made their stop at the post house, and its inner courtyard that still retains the architecture and the 19th atmosphere. The Intendente Palace has now been transformed into a charming hotel.
