Tumbanales I reservoir, patrimonio histórico de Andalucía de importancia todas en Nerva, España (código 01210520059)
Tumbanales I is a gravity dam in Nerva built in 1905 to store water for local supply and agricultural use. The structure sits in a landscape of reddish soil colored by minerals, surrounded by old mining equipment, ruins, metal pipes, and citrus groves along the paths.
The dam was built in 1905 as part of the region's water management system that evolved alongside mining activities. Its construction reflects early engineering efforts to support local industry and provide water for farming communities across the province.
The reservoir connects to the mining heritage of Nerva and reflects the industrial past that shaped the region. Locals and visitors view it as a landmark where communities gather and remember how water management supported the area's development.
The site is best reached on foot via rural paths or by car along secondary roads and works well for slow walks and picnics. Wear sturdy shoes, bring water, and be prepared for uneven terrain and steep sections along the routes.
Small islands sometimes form in the water during dry seasons, revealing how water levels shift with rainfall and seasonal use. Several viewpoints with benches and a distinctive stone lizard sculpture at one overlook give visitors places to pause and survey the landscape.
