The crossing of the Carrión River by the Canal de Castilla, located in Calahorra de Ribas (Palencia), is one of the most emblematic and complex points of this great hydraulic work built between 1753 and 1849. Here, the canal is directly related to the natural river, giving rise to a unique set that also marks the historical beginning of the works of the Canal de Castilla.
Its main function was to regulate the flow of water between the canal and the Carrión River, ensuring navigability, irrigation, and flow control. To achieve this, a remarkable system was constructed, consisting of a diversion dam, spillways, and the well-known Calahorra de Ribas triple lock, comprised of three consecutive oval locks that overcome a significant difference in elevation. These structures, built of solid limestone masonry, display meticulous craftsmanship, with curved walls, semicircular arches, and auxiliary elements for water management.
The complex is well-preserved and continues to serve hydraulic functions, in addition to forming part of the Canal de Castilla, declared a Site of Cultural Interest. Its heritage value lies both in the quality of its construction and in its historical and scenic significance.
A visit to this site offers a glimpse into the technical ingenuity of the 18th century while enjoying a stunning riverside setting. Strolling along the water, observing the workings of the locks, and admiring how the canal blends seamlessly into the landscape makes this an unmissable experience for both cultural and tourist visitors.
