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 modest yet charming suspension bridge is part of the Lakeside Way, the walking and cycling path around Kielder Water. Suspended above the tranquil Lewis Burn, it offers beautiful views of the surrounding pine forest and the rippling water. With its simple steel construction and wooden deck, it is a prime example of functional forest infrastructure—perfectly integrated into the landscape. For cyclists and walkers, it's a lovely spot for a short break, a photo, or simply to reflect on the tranquility of the forest.
