The heritage complex of Lock 42, built between 1831 and 1836, is located within the municipality of Valladolid, at kilometer 138.020 of the Southern Branch of the Castile Canal, easily accessible from the N-620 highway and the La Overuela road. This site played a vital role in the overall canal system: overcoming the difference in elevation, regulating the flow, and organizing the diversion of water to production facilities, while simultaneously ensuring the continuity of the roads.
Several complementary elements associated with the lock complete its functional understanding. The bridge over the lock stands out, with its segmental arch and limestone masonry, featuring well-defined parapets and wing walls, allowing passage for the road to La Overuela. Also present are the diversion bridges, aligned with the main bridge, constructed with semicircular arches of brick and stone masonry, designed to maintain the continuity of the road over the millrace. Completing the ensemble is a historic mill, later converted into a hydroelectric power station, now restored and in good condition. Built of stone, brick, and a wooden structure, it exemplifies the harnessing of energy from the waterfall, alongside the remains of ruined buildings that retain their original layout.
It can be accessed from kilometer 118.300 of the N-620, 60 meters away, or from the La Overuela road. Both roads are linked by a short path that passes over the lock bridge.
