Glenfinnan Viaduct: A Scottish Icon of Engineering and Pop Culture
The Glenfinnan Viaduct, located near the head of Loch Shiel in the Scottish Highlands, is one of Scotland’s most recognisable landmarks. This impressive 21-arch railway viaduct, part of the West Highland Line, spans Glenfinnan and offers stunning views of the surrounding landscape. Built between 1897 and 1901 by engineer Sir Robert McAlpine, the viaduct is not only a marvel of engineering but has also gained worldwide fame due to its appearance in the Harry Potter films as the route of the Hogwarts Express.
A Marvel of Victorian Engineering
Constructed from concrete, the Glenfinnan Viaduct was an engineering feat at the time of its completion. Spanning 380 metres (1,248 feet) and standing 30 metres (100 feet) high, the viaduct carries the West Highland Railway Line across the River Finnan and Glenfinnan valley. Its sweeping curve and multiple arches make it a visually striking structure, seamlessly integrated into the Highland landscape.
The viaduct was designed to support the railway line connecting Fort William to Mallaig, opening up the remote west coast of Scotland to greater travel and commerce. Today, it remains in operation as part of one of the most scenic rail routes in the world, with passengers enjoying views of Loch Shiel, the Glenfinnan Monument, and the surrounding mountains.
A Star of Film and Television
The Glenfinnan Viaduct gained international recognition through its role in the Harry Potter film series, where it is famously crossed by the Hogwarts Express. The viaduct first appears in Harry Potter and the Chamber of Secrets and has since become an iconic location for fans of the series. During the summer months, the Jacobite Steam Train, which operates along the West Highland Line, provides a real-life experience of travelling across the viaduct, evoking the magic of the films.
The viaduct has also appeared in other films and TV shows, contributing to its status as a beloved Highland landmark.
Visiting the Glenfinnan Viaduct
Visitors can view the viaduct from several vantage points. One of the best places to see it is from the Glenfinnan Visitor Centre, which offers information on the viaduct’s history and the surrounding area. From here, a short walk takes visitors to a viewpoint where they can watch the Jacobite Steam Train cross the viaduct, a spectacle that draws hundreds of onlookers daily during the summer months.
For those who prefer a closer view, a trail leads under the viaduct, offering a unique perspective of its towering arches and the engineering behind this iconic structure.
Getting There
The Glenfinnan Viaduct is easily accessible by car via the A830 road, which runs between Fort William and Mallaig. Glenfinnan also has its own railway station on the West Highland Line, making it convenient for travellers exploring the area by train. The Jacobite Steam Train operates from May to October, giving visitors the chance to experience one of Scotland’s most scenic railway journeys and cross the famous viaduct themselves.
