- The cove of Isla Plana in Murcia hides an old fish salting factory and a mysterious underwater cave.
- The El Forau de la Tuta site in Zaragoza has revealed an imperial city with an impressive thermal complex.
- Both sites stand out for their exceptional preservation and the use of advanced digital technology for their study.
Spain is full of places where time seems to have stood still, especially if you know where to look. Sometimes, history isn't found in the most visited museums, but in secluded natural landscapes or small villages where the land decides to return fragments of a glorious past we thought was lost.
From the crystal-clear waters of the Mediterranean to the foothills of the Pyrenees, there are true architectural and archaeological gems that remained hidden for centuries. These relics not only tell us about Roman engineering, but also about how daily life, the economy, and leisure were organized in the far reaches of the Iberian Peninsula.
The underwater secret of Cala de Isla Plana
If we travel to the coast of Murcia, specifically to the Cartagena coastline, we find a place that is a true gem for nature lovers. Isla Plana cove is a tranquil spot, with turquoise waters and an enviable peace , ideal for escaping the crowds of busy beaches.
But the real attraction isn't on the sand, but underwater. The bravest divers can explore the Water Cave, a partially submerged space with narrow passageways that create an almost mystical atmosphere. It's a technical challenge that only experts usually master, where light barely penetrates and silence reigns.
A short distance from this cave, the sea guards a historical treasure: the remains of an ancient fish-salting factory . This complex, active between the 1st and 4th centuries AD, was fundamental to the Roman economy, as it was here that fish was processed to create the famous garum, the sauce that was so fashionable in the Empire and exported to all the provinces.
Besides its history, the surrounding area is a biodiversity paradise. The seagrass meadows teem with life, with octopuses, sea urchins, and all kinds of fish, making this cove a key spot for snorkeling and observing Mediterranean wildlife in its almost pristine state.
The Forau de la Tuta: A city that awoke in Zaragoza
Changing scenery completely, we move towards Artieda, in the Aragonese Jacetania region. Here, one of the most striking discoveries of recent times has been made: the El Forau de la Tuta archaeological site. We are not talking about a simple villa, but a Roman urban center from the Imperial period that forces us to rethink everything we thought we knew about settlement patterns in the western Pre-Pyrenees.
Although some clergymen and scholars had already mentioned remains in the 18th and 20th centuries, it wasn't until 2018 that a serious investigation was launched. Thanks to the collaboration of various institutions, an urban layout of about 4 hectares was discovered , complete with organized streets and sewers, all integrated into a terrace overlooking the Aragón River.
One of the most striking aspects of this discovery is the thermal baths complex. In its reception area, or vestibulum, an exceptional black and white mosaic has been found . The piece depicts a marine thiasos with erotes riding seahorses, dolphins, and scallop shells. The most unusual feature is the inverted two-tone color scheme , with white figures on a black background, something very uncommon in the area.
To understand the scale of this site, archaeologists have used cutting-edge technology. Through LiDAR analysis and laser scanners, they have created a digital twin of the site , allowing researchers and the public to analyze the city without endangering the original structures.
The identity of the Vascones and the Roman legacy
The Forau de la Tuta is not just stone and mosaics; it is an open book about the Vascon people. The site was located on a strategic route connecting Jaca with Pamplona and the Pyrenees. The funerary inscriptions found reveal names such as Agirnes and Ausagesius, which clearly belong to the Aquitanian-Vascon linguistic area.
It is fascinating to observe the social evolution of its inhabitants. At first, they were indigenous people who did not have Roman citizenship, but over time, especially during the Flavian period, these inhabitants became Romanized and became citizens with fully Latin names, although they retained their roots.
The city reached its peak between the 1st and 2nd centuries, but began to decline in the 4th century. Interestingly, the place was not left empty; during the Middle Ages, the area was once again inhabited by a farming village , demonstrating that this enclave has always been attractive to live in, regardless of who held power.
This collection of discoveries, from the submerged salting works of Murcia to the thermal baths of Zaragoza, reveals a map of Roman Hispania far more complex and rich than we had imagined. The combination of untamed nature and scientific rigor allows us to rediscover these corners of the world, which, though unknown to the masses of tourists, are fundamental pillars of our historical identity.
