Knaresborough Viaduct, Railway viaduct in Knaresborough, England.

Knaresborough Viaduct is a stone railway bridge crossing the River Nidd with four arches and three piers. It carries regular passenger trains on the Harrogate line and features castellated walls that line its length.

The original bridge collapsed into the River Nidd in 1848, prompting workers to rebuild it with stone from the Abbey Crags quarry in 1851. This reconstruction made it a key railway connection across North Yorkshire.

The structure shows Victorian engineering skill and fits harmoniously with the medieval castle through its design. It represents how the railway modernized the region and connected small towns to larger cities.

The viaduct is visible from the main road in Knaresborough and offers good views from nearby riverside areas. Visitors can get the best views for photography from across the river or from surrounding parks.

The center pier stands directly in the River Nidd, creating a distinctive reflection that changes with the light and seasons. This feature makes it a favorite subject for photographers visiting the area.
