The Kielder Viaduct in Northumberland is a masterpiece of Victorian railway engineering from the 19th century, with seven skewed stone arches and an ornate baronial style replete with battlements and loopholes—custom-built for the Duke of Northumberland. Once transporting coal and timber to Scotland, it is now a monumental jewel on Kielder Reservoir, saved from demolition and reborn as part of the Lakeside Way: a scenic walkway. The viaduct is not only technically impressive but also culturally enriched with ornate wrought iron panels, designed by children and forged by local craftspeople.

This dramatic and historic landmark is tucked amongst the trees on the edge of Kielder village. The viaduct was built in 1862 to extend the route of the Border Counties railway line into Scotland. The railway company wanted to build it across the River North Tyne in front of the Duke of Northumberland's hunting lodge at Kielder Castle. Apparently the Duke insisted it should reflect the castle's Gothic style, hence why the structure is decorated with battlements and false arrow slits.

It is a dramatic and historic landmark tucked amongst the trees on the edge of Kielder village.
