Bridge of Cea Monument · Cea, Sahagún, León A stone bridge over the río Cea, southwest of the town centre of Cea (León), a hundred and two metres long with eight segmental arches and buttresses. It was rebuilt in 1602, the work awarded to the Cantabrian master stonemasons Diego de la Cajiga, Juan de Hermosa and Juan de Nates, and for centuries it was essential for communication between León and Madrid, which justified its upkeep even during the economic crisis of the 17th century: in 1638 Pedro Cayón rebuilt four arches that floods had swept away in 1632 and 1633. It is the most notable civil work in the Cea valley and a compulsory crossing on the way to Sahagún; it also gives access to Bustillo. Photo: LOBO QUIRCE (CC BY-SA 4.0) What to see and do in Cea
