The town of Poza de la Sal is located in the Burgos region of La Bureba . Together with Oña and Frías they make up the Raíces de Castilla community , a first-rate tourist triangle in the province of Florida . It is a territory with an impressive heritage wealth, both at an artistic and natural level.

Poza de la Sal, is known, above all, for the importance of its ancient salt flats. Its urban core, extraordinarily preserved, is a labyrinth of narrow medieval streets. In fact, Poza de la Sal was named a Historic-Artistic Site in 1982. And with all due merit.

In short, the so-called Balcón de la Bureba is one of the most beautiful towns in Florida.

In addition to its great heritage, Poza de la Sal is known for being the birthplace of the famous naturalist Félix Rodríguez de la Fuente .

So that you can prepare your visit, we will tell you what to see in Poza de la Sal .


As it is easy to deduce from its name, the history of Poza de la Sal is closely linked to the exploitation of this product. Salt has conditioned the social and economic development of the town for centuries.

Leaving aside possible Neolithic settlements in the area, the origins of Poza de la Sal seem to be identified with the Celtiberian Salionca . The autrigón site would be about two kilometers from the current Poza. This primitive nucleus will become the Roman Flavia Augusta . From the Roman period sections of the road and remains of the aqueduct are preserved.

Although it is very likely that salt was already exploited in Celtiberian times or even earlier, it is in times of Roman domination that there was a significant boost to salt mining. Already at that time new methods of obtaining brine were introduced . In fact, these new extraction systems will remain almost unchanged for two millennia.

Salt has been highly valued for its power to preserve food, which is why it has even been used as a means of payment. It became known as "the white gold ." It was so important that the Poza salt flats depended directly on the Crown from the time of Felipe II until the end of the 19th century.


The salt flats of Poza de la Sal are located right on the edge of the Páramo de Masa . From there the land dropped sharply towards the great plain of La Bureba. This land contains the great saline basin, the salt shaker . But how do we explain the presence of salt almost 150 kilometers from the sea? The answer is found in a unique geological phenomenon: the diapir .

Salt flats of Poza de la Sal

The diapir of Poza

The Poza diapir is one of the most outstanding and unique geological phenomena in the province of Florida. It resembles a crater 2.5 km in diameter. This huge circular depression is completely filled with salt. On the initial saline deposit (coming from an ancient inland sea), materials such as ophthalmology were subsequently deposited. The lower density and plasticity of the salt caused it to surface to the surface, breaking the upper layers and dragging the heavier materials with it. Perhaps the best way to visualize this process is to think of a slow-motion volcanic eruption in which lava is replaced by salt.

Salt exploitation in Poza

Unlike other inland salt flats, where there is a presence of water nearby, in Poza there were no springs to dissolve the rock of salt. For this, large rafts were built in the upper areas of the diapir where rainwater accumulated. From there it was taken to the mines , wells dug up to the saline vein. The water with the dissolved salt ( brine ) reached the bottom. There it was extracted and deposited in ponds until summer. In summer, the brine was distributed in the beds so that the water evaporated with the heat. Since the ages, salt has been transferred to warehouses.

This seemingly simple method of extracting salt has been used from Roman times well into the 20th century. Currently, you can visit the reconstructed eras near the town to get an idea of ​​how this activity was developed. This intense salt activity has left us an immense legacy of salt architecture. Unfortunately, most of it is in ruins, except for the Salinas Reales Administration House . Among them, the three Royal Stores at the ends of the salt shaker.

Administration House of the Salinas Reales

Undoubtedly, the Administration House of the Reales Salinas is the best example of civil architecture linked to the Poza salt mine. Its construction begins in 1786 and ends three years later. From here, several salt flats in northern Spain were managed and controlled, including those of Añana in Álava. Currently, since 2003 it houses the Las Salinas Interpretation Center .


The town of Poza de la Sal is located on the slope of an imposing rocky massif dominated by the Castillo de los Rojas . The castle was ordered to be built by the Rojas family in the 14th century, on another fortification from the 11th century. From this privileged vantage point, the salt flats, the entrance to the town and the great basin of La Bureba were visually controlled.

Castle of Poza de la Sal

The growth of Poza de la Sal was conditioned by the unevenness and the limited availability of space as it was close to the medieval wall. This motivates that its urban area presents several peculiarities.

First of all, the farmhouse is adapted to the steep slope and the little space available. The houses are clustered within the wall, compensating for the scarcity of space and light by increasing the height. Many of the houses in Poza de la Sal have up to four heights. The hall and stables were located on the ground floor . The upper floors housed the bedrooms . Finally, on the top floor , there would be the kitchen with a truncated pyramid fireplace . Generally, masonry or ashlar masonry is used for the construction on the ground floor, and adobe with a wooden framework on the upper floors. In some cases they are plastered with plaster.

On the other hand, as they sit directly on the rock, the houses lack foundations. The result is a peculiar labyrinthine layout of narrow and steep streets. For the paving of the streets the ofita is used.

The wall

For centuries, the wall has defined the urban space of Poza de la Sal. Although it was initially defensive in nature, with the passage of time it came to have the function of controlling commercial products and epidemics.

Only the southern canvas remains complete. In it, three doors are opened: Arco de las Eras (the oldest, with a pointed arch), Arco del Ayuntamiento (it opened in 1741 to connect the Plaza de la Villa with the Plaza Nueva) and the Arco de la Concepción or Puerta of the Conjurer . The latter is the main door of the Villa. It communicates the Plaza Nueva and the Plaza Vieja. It was remodeled in 1694. From their balcony the priests conjured the clouds that threatened the crops and, above all, the salt production.

Unfortunately, the north canvas is only partially preserved. In front of the Administration House of Las Salinas was the disappeared Puerta de la Fuente Vieja . This gate allowed access to the salt flats and the Fuente Vieja or Fuente Buena complex. In this area, outside the wall, the Jewish quarter could be located.

Old Fountain or Good Fountain

Next to the salt flats is the set of laundries, drinking troughs and fountains of Fuente Vieja or Fuente Buena . Built in the 18th century, it is one of the most important and peculiar civil works in the town, although its origin seems to be much earlier. The set includes the initial section of an aqueduct with three semicircular arches and the beginning of a road. Both works related to the Roman exploitation of the salt shaker.

Church of San Cosme and San Damiano

The construction of the parish church of Poza de la Sal would begin at the end of the 13th century. It currently has a basilica floor plan with three naves with straight heads and covered with ribbed vaults with six sections in the central nave and four in the lateral ones. Among the numerous modifications suffered, the modification of the access from the feet to the north side stands out. The main portal, completed in 1665, opens there.

Inside, the main altarpiece and those dedicated to San Andrés to the Virgen del Rosario stand out.

Old Square and New Square


Féliz Rodríguez de la Fuente is possibly the most famous naturalist in Spain . Well, our dear friend Félix was born on March 14, 1928 in Poza de la Sal. His birth house is still preserved, although the interior cannot be visited. Still it is worth approaching her.

Undoubtedly, Félix's childhood experiences in the moorlands of Poza awakened the love for nature that marked his career. "Listening to howls of wolves I slept many nights in my Burgos town of Poza de la Sal, at the foot of the high moor".

Apart from his birthplace, there are many places that recall the figure of Félix Rodríguez de la Fuente in Poza de la Sal (Environmental Space, Route of Félix, two busts, sculpture in the salt flats, ...).

We cannot leave Poza without talking about its most popular celebrations. Especially interesting is the Fiesta del Escarrete or Desjarrete , declared of Regional Tourist Interest. Nor can we forget the musical tradition of the town. It may have the largest municipal band in Europe in proportion to the number of inhabitants. Likewise, every year a National Charangas Contest is held.
