Pylons of Cádiz, Overhead power line crossing in Cádiz Province, Spain.
The Pylons of Cádiz are two steel transmission towers standing 158 meters high, carrying high-voltage power lines across the Bay of Cádiz and connecting Puerto Real to the city center. Their hollow shafts taper from the base to the top and feature internal helical staircases for maintenance access.
Construction of these steel pylons began in 1957 during Franco's regime, following designs by Italian engineer Alberto M. Toscano. The project emerged from the need to address the region's growing energy requirements.
The steel structures show how the city modernized its infrastructure in the mid-20th century and adapted to growing energy demands. Their industrial form still shapes the landscape of the bay today and stands as a reminder of that modernization period.
The towers are visible from the bay and best observed from the water or elevated spots along the shoreline. Plan time to appreciate their scale and technical structure from different vantage points.
Notably, these towers operate without a ground conductor in the span between them, which is an unusual technical feature. Instead, six monopolar strainers at each portal handle the power transmission.
