The name 'Puentedey' is derived from 'Puente de Dios' or 'Bridge of God'.
The limestone rock formation is approximately 15 meters high.
The village was established in the medieval period, taking advantage of the natural bridge as a defensive site.
The Nela River provides a consistent water flow that has shaped the subterranean karst gallery.
Puentedey has been recognized as a site of Geological Interest of Spain (LIG).
Archaeological findings in the vicinity suggest human occupation of nearby caves dating back to the Bronze Age.
The Nela River Natural Bridge is a limestone rock formation in Puentedey, Burgos, that spans the Nela River, which carved the tunnel through the cliffside over millions of years. The village of Puentedey sits directly atop this natural arch, with many stone houses built onto the rock itself. It is a key geological feature of the Las Merindades region. The village is classified as one of the 'Pueblos más bonitos de España'. The surrounding terrain is characterized by high karst landscapes and dense oak forests. The site remains accessible as a public space integrated into the village layout.
