Drought Reveals Ancient Sunken Village in La Rioja, Spain 2026

The drought has revealed the ancient sunken village of Mansilla de la Sierra in La Rioja, Spain, as the reservoir's water level drops dramatically. Walls, moss-covered stone arches, and the layout of old streets have emerged from the Mansilla reservoir, located between Mansilla de la Sierra and Villavelayo, about 70 kilometers from Logroño. According to EFE on October 25, the old village has resurfaced in the Najerilla reservoir, offering a stark contrast to earlier this year when the reservoir was nearly full.

What Caused the Village to Reappear?

The reservoir's water level has plummeted due to a severe drought. In February, after doubling its reserves in just three weeks, the reservoir was at 89% capacity, holding about 68 million cubic meters of water. Eight months later, weekends see buses of visitors walking among the mud and ruins. This dramatic swing highlights the region's vulnerability to prolonged dry spells.

Why Does This Matter?

The receding water exposes not just a curiosity but a significant archaeological site. The village of Mansilla de la Sierra was relocated in the 16th century to the banks of the Gatón River, and the old church of Santa Catalina remained on the shore. Since 2016, archaeologists have been excavating next to the ermita de Santa Catalina, the only building left standing. They have uncovered the apse and presbytery of a Romanesque church that served as the medieval parish church. Beneath it, three overlapping temples and a late-Roman building have been found, along with Celtiberian and Roman pottery. Carbon-14 dating places a fire in the first church between 576 and 654 AD.

What Does the Emergence Reveal?

The exposed ruins include stone arches, petrified tree remains, and the grid of ancient streets. These remnants offer a tangible link to the past, drawing visitors and researchers alike. The site is not the original Mansilla but a later iteration, yet it provides valuable insights into medieval and ancient settlement patterns in the region.
