The city of Rio Maior has one of the most unusual natural phenomena in Portugal and continues to attract visitors because of some inland salt pans where the water is seven times saltier than the sea. About 80 kilometers from Lisbon, this place keeps alive a centuries-old tradition linked to salt extraction and has become one of the region’s main visiting cards.
According to the travel blog, the Rio Maior Salt Flats are the only inland salt pans in Portugal and are located in the Serras de Aire e Candeeiros Natural Park. Although the city is located about 30 kilometers from the ocean, it is there that a brine with a salt concentration well above sea water is born.
The phenomenon takes place in the so-called Poço das Marinhas do Sal, from which extremely salty water flows that feeds the entire farm. According to the same source, this characteristic allows the natural crystallization of salt and continues to surprise many visitors who arrive in the region without imagining finding a scene of this type so far from the coast.
The “white gold” that spanned centuries
The exploration of these salt pans has been documented since 1177, in records attributed to the Order of Santiago. The blog writes that, for several centuries, the salt extracted in Rio Maior played an important role in the local economy and was used as a strategic product and exchange currency.
According to the same source, the salt-making tradition was passed down between generations and ended up shaping the identity of the municipality. Even today, traditional structures remain visible and help to preserve an image closely linked to the history of the region.
Wooden houses that gained new life
One of the most characteristic elements of the salt flats are the small wooden houses scattered near the salt butchers. Initially, these spaces functioned as warehouses used by salt mining families to store the production collected throughout the season.
Today, many of these constructions have different functions. It is important to note that many of these houses have been transformed into craft shops, small cafes and restaurants, helping to make the area more attractive for those who visit Rio Maior throughout the year.
Ideal time to visit the salt flats
Anyone who wants to observe the salt formation process should choose the warmer months. According to the same source, the period between May and October is considered the best time to see the tanks filled with brine and watch the natural crystallization of the salt.
During this phase, it is possible to better understand how the entire activity linked to collecting the so-called “white gold” works. The travel blog adds that this continues to be one of the most sought after experiences by visitors passing through the city.
Much more than just salt
In addition to the salt flats, Rio Maior brings together several points of historical and cultural interest. According to the same source, the Villa Romana is one of the most emblematic places in the city, standing out for its mosaics, columns and archaeological objects linked to the Roman presence in the region.
The city also includes spaces such as Parque do Rio, Praça do Comércio and Casa Senhorial d’El Rei D. Miguel, currently transformed into a cultural space. These places help to show different phases of Rio Maior’s history and complement the visit to the salt flats.
Between heritage and nature
The Misericórdia Church is another of the buildings highlighted in the city’s itinerary, mainly due to its 17th century tiles and carved stone altars. The Chapel of Nossa Senhora da Vitória also remains one of the best-known historical points in the municipality.
Parque 25 de Abril appears as one of the most popular green areas for walks and moments of rest. As a whole, Rio Maior maintains a combination of heritage, tradition and nature that continues to arouse curiosity among those looking for different destinations near Lisbon.
